报告服务网络凭据

Question

收到错误：

  

“属性或索引器   'Microsoft.Reporting.WebForms.IReportServerCredentials.NetworkCredentials'   无法分配 - 它只读“

在这一行：

  

reportviewer1.ServerReport.ReportServerCredentials.NetworkCredentials   =新的System.Net.NetworkCredential（“someaccount”，   “somepassword”）;

当我将光标悬停在NetworkCredentials上时，它会显示：“获取或设置用于使用报表服务器进行身份验证的网络凭据”..

到底发生了什么事？

感谢

Answer 1

this.rpv.ServerReport.ReportServerCredentials不是只读的。阅读这篇文章：

Answer 2

它仍然是只读的，ReportServerCredentials字段仍然是只读的，它只有getter而不是setter！

Answer 3

将此类添加到同一名称空间：

 public class CustomReportCredentials : IReportServerCredentials
 {
     private string _UserName;
     private string _PassWord;
     private string _DomainName;

 public CustomReportCredentials(string UserName, string PassWord, string DomainName)
     {
        _UserName = UserName;
        _PassWord = PassWord;
        _DomainName = DomainName;
     }

     public System.Security.Principal.WindowsIdentity ImpersonationUser
     { 
        get { return null; } 
     } 

     public ICredentials NetworkCredentials
     {
        get { return new NetworkCredential(_UserName, _PassWord, _DomainName); }
     }

      public bool GetFormsCredentials(out Cookie authCookie, out string user,
      out string password, out string authority)
      {
        authCookie = null;
        user = password = authority = null;
        return false;
     }
}

然后设置您的凭据：

IReportServerCredentials Creds = new CustomReportCredentials("Administrator", "password", "domain"); //to actual values
myReportViewer.ServerReport.ReportServerCredentials = Creds;
