我正在使用Aspose在CRM Dynamics 2011 Microsoft幻灯片中生成动态内容。即使代码中的逻辑似乎是正确的并且不应产生 null 或空值，数据也没有正确填充多个字段和关系，并且我已经确认数据库中确实有字段的数据（数据确实正确填充了某些字段和关系）。 所有这些问题都发生在Powerpoint本身开始生成之前，因此实际上这些问题可能不是"Aspose"问题，它们可能只是异步检索数据的Web服务/CRM问题。
幻灯片工作流程：
1） HTML Web 资源包含一个用于下载 PowerPoint 报告的
Silverlight 按钮2） 在按钮上单击Silverlight应用程序 通过Web服务请求
异步收集CRM中的项目实体所需的所有数据3）数据被编译成一个项目类，然后传递给ReportGenerator服务，并使用这些数据来填充PowerPoint的各个部分（这是我们使用自定义Aspose内容的部分）
4） Aspose 功能遍历每个指定的幻灯片，并在需要时解析它们，并添加数据。5）Powerpoint完成并向用户吐出并填充数据。
这是我在获取数据填充时遇到麻烦的两个示例。 项目。下面的 Pwins 值最终为 null，这告诉我 lambda 表达式没有正确执行，它在方法结束时仍然是 null，这告诉我突出显示的行甚至根本没有执行。
示例 1：
/// <summary>
/// Retrieves and stores information required for P(win) report, and then tries to send a web service request.
/// </summary>
/// <param name="service"></param>
private void LoadPwin(ReportServiceClient service)
{
string filter = string.Format("?$filter=sfa_Project/Id eq guid'{0}'", GetProjectId());
string url = GetEntitySetAddress("sfa_pwin_competitor") + filter;
WebClient client = new WebClient();
client.DownloadStringCompleted += (sender, args) =>
{
if (args.Error == null)
{
StringReader stream = new StringReader(args.Result);
XmlReader reader = XmlReader.Create(stream);
List<PWin> pwins = new List<PWin>();
List<Dictionary<string, string>> dictionaries = LoadEntitiesFromXml(reader);
foreach (Dictionary<string, string> dictionary in dictionaries)
{
PWin pwin = new PWin();
pwin.CompanyName = ParseDictionaryValue(dictionary["sfa_competitor"]);
pwin.IsBoeing = (ParseDictionaryValue(dictionary["sfa_is_boeing"]) == "true");
pwin.IsDomestic = (ParseDictionaryValue(dictionary["sfa_domestic_or_international"]) == "true");
pwin.AffordabilityWeight = ParseDictionaryValueToNumber(dictionary["sfa_affordability_weight"]);
pwin.AffordabilityScore = ParseDictionaryValueToNumber(dictionary["sfa_affordability_score"]);
pwin.CustomerRelationshipWeight = ParseDictionaryValueToNumber(dictionary["sfa_customer_relationship_weight"]);
pwin.CustomerRelationshipScore = ParseDictionaryValueToNumber(dictionary["sfa_customer_relationship_score"]);
pwin.CustomerAdvantageWeight = ParseDictionaryValueToNumber(dictionary["sfa_customer_advantage_weight"]);
pwin.CustomerAdvantageScore = ParseDictionaryValueToNumber(dictionary["sfa_customer_advantage_score"]);
pwin.CompetitionWeight = ParseDictionaryValueToNumber(dictionary["sfa_competition_weight"]);
pwin.CompetitionScore = ParseDictionaryValueToNumber(dictionary["sfa_competition_score"]);
pwin.CPOBCWeight = ParseDictionaryValueToNumber(dictionary["sfa_cpobc_weight"]);
pwin.CPOBCScore = ParseDictionaryValueToNumber(dictionary["sfa_cpobc_score"]);
pwin.CompanyResourcesWeight = ParseDictionaryValueToNumber(dictionary["sfa_company_resources_weight"]);
pwin.CompanyResourcesScore = ParseDictionaryValueToNumber(dictionary["sfa_company_resources_score"]);
pwin.CompanyResourcesInvestmentWeight = ParseDictionaryValueToNumber(dictionary["sfa_company_resources_investment_weight"]);
pwin.CompanyResourcesInvestmentScore = ParseDictionaryValueToNumber(dictionary["sfa_company_resources_investment_score"]);
pwin.ProgramBackgroundWeight = ParseDictionaryValueToNumber(dictionary["sfa_program_background_weight"]);
pwin.ProgramBackgroundScore = ParseDictionaryValueToNumber(dictionary["sfa_program_background_score"]);
pwin.ContinuityOfEffortWeight = ParseDictionaryValueToNumber(dictionary["sfa_continuity_of_effort_weight"]);
pwin.ContinuityOfEffortScore = ParseDictionaryValueToNumber(dictionary["sfa_continuity_of_effort_score"]);
pwin.ExecutionWeight = ParseDictionaryValueToNumber(dictionary["sfa_execution_weight"]);
pwin.ExecutionScore = ParseDictionaryValueToNumber(dictionary["sfa_execution_score"]);
pwin.TechnicalSolutionWeight = ParseDictionaryValueToNumber(dictionary["sfa_technical_solution_weight"]);
pwin.TechnicalSolutionScore = ParseDictionaryValueToNumber(dictionary["sfa_technical_solution_score"]);
pwin.StrategyToWinWeight = ParseDictionaryValueToNumber(dictionary["sfa_strategy_to_win_weight"]);
pwin.StrategyToWinScore = ParseDictionaryValueToNumber(dictionary["sfa_strategy_to_win_score"]);
pwin.ManagementStrengthWeight = ParseDictionaryValueToNumber(dictionary["sfa_management_strength_weight"]);
pwin.ManagementStrengthScore = ParseDictionaryValueToNumber(dictionary["sfa_management_strength_score"]);
pwin.CustomerPercievedCommitmentWeight = ParseDictionaryValueToNumber(dictionary["sfa_customers_percieved_commitment_weight"]);
pwin.CustomerPercievedCommitmentScore = ParseDictionaryValueToNumber(dictionary["sfa_customers_percieved_commitment_score"]);
pwin.PastPerformanceWeight = ParseDictionaryValueToNumber(dictionary["sfa_past_performance_weight"]);
pwin.PastPerformanceScore = ParseDictionaryValueToNumber(dictionary["sfa_past_performance_score"]);
pwin.RawPWin = ParseDictionaryValueToDecimal(dictionary["sfa_pwin_score"]);
pwin.RelativePWin = ParseDictionaryValueToDecimal(dictionary["sfa_relative_pwin_score"]);
pwins.Add(pwin);
}
project.PWins = new ObservableCollection<PWin>(pwins);
PwinReady = true;
reader.Close();
TrySendRequest(service);
}
};
client.DownloadStringAsync(new Uri(url));
}
示例 2 项目。下面的团队成员值最终为空：
/// <summary>
/// Retrieves and stores information required for Capture Team Roster report, and then tries to send a web service request.
/// </summary>
/// <param name="service"></param>
private void LoadCaptureTeamRoster(ReportServiceClient service)
{
string filter = string.Format("?$select=sfa_name,sfa_Role&$filter=sfa_Project/Id eq guid'{0}'", GetProjectId());
string url = GetEntitySetAddress("sfa_team_roster") + filter;
WebClient client = new WebClient();
client.DownloadStringCompleted += (sender, args) =>
{
if (args.Error == null)
{
StringReader stream = new StringReader(args.Result);
XmlReader reader = XmlReader.Create(stream);
List<TeamMember> members = new List<TeamMember>();
List<Dictionary<string, string>> dictionaries = LoadEntitiesFromXml(reader);
foreach (Dictionary<string, string> dictionary in dictionaries)
{
TeamMember member = new TeamMember();
member.Name = ParseDictionaryValue(dictionary["sfa_name"]);
member.Role = ParseDictionaryValue(dictionary["sfa_role"]);
members.Add(member);
}
project.TeamMembers = new ObservableCollection<TeamMember>(members);
CaptureTeamRosterReady = true;
reader.Close();
TrySendRequest(service);
}
};
client.DownloadStringAsync(new Uri(url));
}
下面是另一个示例，它不是关系的问题，而是在 CRM 中的项目实体上填充的字段的问题，该字段在检索数据后显示为空。 CaptureTeamLeader和ProgramManager最终都是空字符串，但是ProjectName和ProjectNumber
填充没有问题 private void LoadCampaignTitle(ReportServiceClient service)
{
project.ProjectName = GetAttributeValue("sfa_name");
project.ProjectNumber = GetAttributeValue("sfa_project_number");
project.CaptureTeamLeader = GetAttributeValue("sfa_capture_team_leader_emp");
project.ProgramManager = GetAttributeValue("sfa_program_manager_emp");
CampaignTitleReady = true;
TrySendRequest(service);
}
任何帮助将不胜感激。 提前感谢！
编辑：
这是请求的属性值方法：
/// <summary>
/// Gets the value of provided attribute from the current page's Xrm data. If for any reason the retrieval fails, returns an empty string.
/// </summary>
/// <param name="attributeName"></param>
/// <returns></returns>
private string GetAttributeValue(string attributeName)
{
// NOTE: This is the preferred way to retrieve data from the CRM. However for some unknown issue,
// this always returns NULL. It will be replaced with directly calling .eval to the window object.
// dynamic Xrm = (ScriptObject)HtmlPage.Window.GetProperty("window.parent.Xrm");
try
{
return HtmlPage.Window.Invoke("getAttributeValue", attributeName).ToString();
}
catch (ArgumentNullException)
{
return string.Empty;
}
catch (ArgumentException)
{
return string.Empty;
}
catch (InvalidOperationException)
{
return string.Empty;
}
}
这个问题的解决方案是数字 1 下载字符串异步和我代码中的其他地方正在异步执行操作，因此调试器将我抛弃并显示为 null，而它们实际上只是稍后执行。 实际修复需要对托管 Web 服务的文件夹中的客户端.xml文件进行一些更改。
