オブジェクトの現在の状態のため、操作は無効ですか？

Question

私はVisual Studio 2008で以下のコードを書いて、シェイプポイントで新しいWebアプリケーションをプログラムで作成し、invalidOperationExceptionの下で「操作がオブジェクトの現在の状態のため有効ではありません。

using System; 
using System.Configuration; 
using System.Data; 
using System.Linq; 
using System.Web; 
using System.Web.Security; 
using System.Web.UI; 
using System.Web.UI.HtmlControls; 
using System.Web.UI.WebControls; 
using System.Web.UI.WebControls.WebParts; 
using System.Xml.Linq; 
using Microsoft.SharePoint.Administration; 
using Microsoft.SharePoint; 

public partial class _Default : System.Web.UI.Page 
{ 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     SPSecurity.RunWithElevatedPrivileges(delegate() 
     { 
     SPWebApplicationBuilder webAppBuilder = new SPWebApplicationBuilder(SPFarm.Local); 

     SPWebApplication newApplication; 
     int myPort = 20002; 

     webAppBuilder.Port = myPort; 
     webAppBuilder.RootDirectory = new System.IO.DirectoryInfo("C:\\Inetpub\\wwwroot\\wss\\VirtualDirectories\\" + myPort); 
     webAppBuilder.ApplicationPoolId = "AppPool1"; // application pool 

     webAppBuilder.ApplicationPoolUsername = "Anant_Raj"; 
     System.Security.SecureString password = new System.Security.SecureString();     

     string strName = "#ana123";     

     char[] pass = strName.ToCharArray();     

     foreach (char c in pass)     

     password.AppendChar(c);    

     webAppBuilder.ApplicationPoolPassword = password; 

     webAppBuilder.CreateNewDatabase = true; // Create new database    

     webAppBuilder.DatabaseName = "wss_site2011_content"; // database name    

     webAppBuilder.DatabaseServer = webAppBuilder.DefaultZoneUri.Host; //Host name/computer name   

     webAppBuilder.UseNTLMExclusively = true; // Use NTLM authentication 
     webAppBuilder.AllowAnonymousAccess = true; 
     newApplication = webAppBuilder.Create(); // Create new web application 
     newApplication.Provision();   //Provision it into web farm 
     }); 

    } 
} 

何か提案がありますか？

このようなものを試してみてください。

protected void Page_Load(object sender, EventArgs e) 
{ 
    SPWebApplicationBuilder webAppBuilder; 
    SPWebApplication newApplication; 

    // Only the objects creation in the RunWithElevatedPrivileges block 
    SPSecurity.RunWithElevatedPrivileges(delegate() 
    { 
     webAppBuilder = new SPWebApplicationBuilder(SPFarm.Local); 
    }); 

    // other statement outside the RunWithElevatedPrivileges block 

    int myPort = 20002; 

    webAppBuilder.Port = myPort; 
    webAppBuilder.RootDirectory = new System.IO.DirectoryInfo("C:\\Inetpub\\wwwroot\\wss\\VirtualDirectories\\" + myPort); 
    webAppBuilder.ApplicationPoolId = "AppPool1"; // application pool 

    webAppBuilder.ApplicationPoolUsername = "Anant_Raj"; 
    System.Security.SecureString password = new System.Security.SecureString();     

    string strName = "#ana123";     

    char[] pass = strName.ToCharArray();     

    foreach (char c in pass)     

    password.AppendChar(c);    

    webAppBuilder.ApplicationPoolPassword = password; 

    webAppBuilder.CreateNewDatabase = true; // Create new database    

    webAppBuilder.DatabaseName = "wss_site2011_content"; // database name    

    webAppBuilder.DatabaseServer = webAppBuilder.DefaultZoneUri.Host; //Host name/computer name   

    webAppBuilder.UseNTLMExclusively = true; // Use NTLM authentication 
    webAppBuilder.AllowAnonymousAccess = true; 
    newApplication = webAppBuilder.Create(); // Create new web application 
    newApplication.Provision();   //Provision it into web farm 
}
