What is xp_SaveXML?

There is a chance that your problem is there, although without seeing the code it is difficult to be sure.

Does the user running your code have permissions to create a file in c:\Temp?

i jst add the read write permission to the directory
..
and xp_saveXml is my clr stored procedure

MSIL

[Microsoft.SqlServer.Server.SqlProcedure]
   public static void xp_SaveXML(string  XmlData, String Filename)
   {
       try
       {
           FileIOPermission(FileIOPermissionAccess.AllAccess, Filename);
           PermissionSet(PermissionState.Unrestricted);
           ps.AddPermission(fp);
           File.WriteAllText(Filename, XmlData);
           XmlDocument xmlDoc = new XmlDocument();
           SqlPipe output = SqlContext.Pipe;
           xmlDoc.LoadXml(XmlData);
           xmlDoc.Save(Filename);
       }
       catch (Exception ex)
       {
           SqlContext.Pipe.Send("Error writing to file " + ex.Message);
       }
   }
