错误 CS0119：'ServiceClient' 是一种类型，在给定上下文中无效

Question

我得到错误CS0119:"ServiceClient"是一种类型，在我的项目中的给定上下文中无效。在我的项目中，我有一个网络参考，在那里我得到了这个错误。详细信息如下。请帮帮那些家伙，因为我不知道如何解决这个问题。

代码

private ServiceClient _client;
private ServiceClient ProfileServiceClient
{
get
{
if (_client == null)
{
//Log.Trace("Initiating Profile client");
var watch = Stopwatch.StartNew();
ServiceClient _client = new ServiceClient ();
watch.Stop();
Log.Debug("Initiating Profile took " + watch.ElapsedMilliseconds + " miliseconds");
}
return _client;
}
}

public AuthenticatedUser ResolveUser(string Id)
{
try
{
//Log.BusinessTask(string.Format("Trying to resolve '{0}' via Profile", vcnId));
var temp = ServiceClient .getProfileUser(Id, Config.ProfileAppName);
if (temp == null)
{
Log.BusinessTask(string.Format("No user found in profile with '{0}' as  ID", Id));
var dummyUser = new AuthenticatedUser()
{
Id = Id,
Email = string.Empty,
FirstName = Id,
LastName = string.Empty
};
dummyUser.Roles.Add("Viewer");
Log.BusinessTask("Closing Profile client connection");
ServiceClient .Dispose();
return dummyUser;
}
Log.BusinessTask("Profile user found, mapping properties");
var result = new AuthenticatedUser
{
Id = temp.userNr,
Email = temp.email,
FirstName = temp.firstName,
LastName = temp.lastName
};
result.Roles.Add("Viewer");
Log.BusinessTask("Profile user found, mapping roles and applications");
var animatrix = ServiceClient .getTheAnimatrix(Id, Config.ProfileAppName, 0, null, null);
if (animatrix != null)
{
foreach (var matrix in animatrix)
{
if (matrix.authorisations != null)
{
foreach (var m in matrix.authorisations)
{
if (m.value.strValue == "Developer Documentation")
{
if (!result.Roles.Any(x => x.Equals("Developer", StringComparison.InvariantCultureIgnoreCase)))
result.Roles.Add("Developer");
}
if (m.value.strValue == "IsIt Documentation")
{
if (!result.Roles.Any(x => x.Equals("IsIt", StringComparison.InvariantCultureIgnoreCase)))
result.Roles.Add("IsIt");
}
if (m.characteristic == "Managed Application")
{
if (matrix.role.roleName.Contains("DEVELOPER"))
result.Applications.Add("Developer" + "/" + m.value.strValue);
else
result.Applications.Add("IsIt" + "/" + m.value.strValue);
}
}
}
}
}
Log.BusinessTask("Closing Profile client connection");
ServiceClient .Dispose();
Log.BusinessTask("Returning User object");
return result;
}
catch (Exception e)
{
Log.Error(string.Format("Couldn't reach the PROFILE auth webservice : {0}", e));
}
return new AuthenticatedUser { FirstName = "Viewer", Id = "none" };
}

在Referrence.cs文件中

public ServiceClient () {
this.Url = 
global::ProxyComponent.Properties.Settings.Default.ProxyComponent_Services_ServiceClient _ServiceClient ;
if ((this.IsLocalFileSystemWebService(this.Url) == true)) {
this.UseDefaultCredentials = true;
this.useDefaultCredentialsSetExplicitly = false;
}
else {
this.useDefaultCredentialsSetExplicitly = true;
}
}

我在这一行中出错ServiceClient_client=new ServiceClient((。这个错误有什么解决方案或线索吗？在方法AuthenticatedUser ResolveUser(string Id(中，行var temp=ServiceClient.getProfileUser(Id，Config.ProfileAppName(ServiceClient引发错误，类似于引发了类型为"System.TypeInitializationException"的异常。InnerException｛"对象引用未设置为对象实例。｝

解决方案好的，我找到了我的解决方案。我必须更改这条线路

var temp = ServiceClient .getProfileUser(Id, Config.ProfileAppName);

到这个

_client = new ServiceClient();
var temp = _client.getProfileUser(Id, Config.ProfileAppName);

看起来编译器几乎把服务客户端与另一种类型混淆了。也许可以尝试使用具有完整命名空间的ServiceClient？类似FullProjectNamespace.ServiceClient_ServiceClient=new的内容。。。
