来自PHP,我不习惯分配或返回特定类型,因为PHP真的不在乎。但是回到Java和c#的世界这些语言确实关心,当你说传递给我这个类型时它期望那个类型。那么我做错了什么我如何将它创建为类型SPList
我有一个非常基本的功能,如:
protected void createNewList(SPFeatureReceiverProperties properties)
{
Dictionary<string, List<AddParams>> param = new Dictionary<string, List<AddParams>>();
// Create the keys
param.Add("Name", new List<AddParams>());
param.Add("Type", new List<AddParams>());
param.Add("Description", new List<AddParams>());
// Set the values
param["Name"].Add(new AddParams { type = SPFieldType.Text, required = true });
param["Type"].Add(new AddParams { type = SPFieldType.Text, required = true });
param["Description"].Add(new AddParams { type = SPFieldType.Text, required = true });
// Create the really simple List.
new SPAPI.Lists.Create(properties, param, "Fake List", "Sample Description", SPListTemplateType.GenericList, "Sample View Description");
}
这将创建一个列表,一个在web部件激活时的SharePoint 2010列表。名字是Fake List,我们看到我们传入了一些列和它们的参数。让我们看看这个SPAPI.Lists.Create
方法:
public Create(SPFeatureReceiverProperties properties, Dictionary<string, List<AddParams>> columns,
string name, string description, SPListTemplateType type, string viewDescription)
{
SPSite siteCollection = properties.Feature.Parent as SPSite;
if (siteCollection != null)
{
SPWeb web = siteCollection.RootWeb;
Guid Listid = web.Lists.Add(name, description, type);
web.Update();
// Add the new list and the new content.
SPList spList = web.Lists[name];
foreach(KeyValuePair<string, List<AddParams>> col in columns){
spList.Fields.Add(col.Key, col.Value[0].type, col.Value[0].required);
}
spList.Update();
//Create the view? - Possibly remove me.
System.Collections.Specialized.StringCollection stringCollection =
new System.Collections.Specialized.StringCollection();
foreach (KeyValuePair<string, List<AddParams>> col in columns)
{
stringCollection.Add(col.Key);
}
//Add the list.
spList.Views.Add(viewDescription, stringCollection, @"", 100,
true, true, Microsoft.SharePoint.SPViewCollection.SPViewType.Html, false);
spList.Update();
}
}
我们可以在这里看到,我们所做的是创建一个SPList对象在Sharepoint中使用。部署后,我们有一个新的列表,我们可以添加到我们的页面。那么问题是什么呢?
在Php中,我可以将createNewList(SPFeatureReceiverProperties properties)
传递给一个请求SPList类型对象的函数,它会工作(除非我遗漏了什么>.>)这里就像,不,那不是SPList走开。
所以我的问题是:
我需要做什么修改才能既创建列表又返回SPLIst对象?和return new SPAPI.Lists.Create(properties, param, "Fake List", "Sample Description", SPListTemplateType.GenericList, "Sample View Description");
一样简单吗
因为这对我来说是正确的。
将方法签名转为SPList并返回return new ....
不起作用
你需要从你的两个方法中返回一个SPList:
protected SPList createNewList(SPFeatureReceiverProperties properties)
{
//Do the stuff
SPList result = new SPAPI.Lists.Create(properties, param, "Fake List", "Sample Description", SPListTemplateType.GenericList, "Sample View Description");
return result;
}
public SPList Create(SPFeatureReceiverProperties properties, Dictionary<string, List<AddParams>> columns,
string name, string description, SPListTemplateType type, string viewDescription)
{
// Do the stuff
return spList;
}
