報告服務網絡憑據

Question

收到錯誤：

reportviewer1.ServerReport.ReportServerCredentials.NetworkCredentials = new System.Net.NetworkCredential("someaccount", "somepassword");

當我將鼠標懸停在NetworkCredentials光標，它說：這條線內

"Property or indexer 'Microsoft.Reporting.WebForms.IReportServerCredentials.NetworkCredentials' cannot be assigned to-- it is read only"

「獲取或套網絡憑據用於與報告服務器進行身份驗證「..

這裏發生了什麼？

謝謝

Answer 1

this.rpv.ServerReport.ReportServerCredentials不是隻讀的。閱讀此篇：

Answer 2

它仍然是隻讀的，即ReportServerCredentials領域還在只讀的，它只有吸氣而不是setter！

Answer 3

這個類添加到同一個命名空間：

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; 
    } 
} 

然後設置您的憑據是這樣的：

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