我想從ASP.NET應用程序中調用我的服務中的方法,如下所示。ASP.NET客戶端WCF故障排除 - 幫助!
public bool ValidateUser(string username, string password)
{
try
{
// String CurrentLoggedInWindowsUserName = WindowsIdentity.GetCurrent().Name;
// //primary identity of the call
// String CurrentServiceSecurityContextPrimaryIdentityName =
// ServiceSecurityContext.Current.PrimaryIdentity.Name;
//
}
catch (Exception ex)
{
FaultExceptionFactory fct = new FaultExceptionFactory();
throw new FaultException<CustomFaultException>(fct.CreateFaultException(ex));
}
return false;
}
的配置爲我服務的客戶機端是如下
<binding name="WSHttpBinding_IMembershipService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
bypassProxyOnLocal="false" transactionFlow="false"
hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text"
textEncoding="utf-8" useDefaultWebProxy="false" allowCookies="false">
<readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
maxBytesPerRead="4096" maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00"
enabled="false" />
<security mode="Message">
<transport clientCredentialType="Windows" proxyCredentialType="None"
realm="" />
<message clientCredentialType="Windows" negotiateServiceCredential="true"
algorithmSuite="Default" establishSecurityContext="true" />
</security>
</binding>
我一直有問題是,當我把它;我收到以下異常消息。
Server Error in '/' Application.

cannot be used for communication because it is in the Faulted state.

我不完全確定爲什麼我繼續得到這個。以防萬一,這裏是我打電話給我的服務從客戶端
private bool ValidateUserCredentials(string UserName, string Password)
{
bool boolReturnValue = false;
using(Members.MembershipServiceClient client =
new Controls.Members.MembershipServiceClient())
{
try
{
boolReturnValue = client.ValidateUser(UserName, Password);
}
catch (FaultException<CustomFaultException> ex)
{
throw ex;
}
}
return boolReturnValue;
}
任何人有任何想法,我需要在這種情況下怎麼辦?
