C＃更新statment失败错误：_COMPlusExceptionCode = -532459699

Question

我有更新的表如下方法：

public static Boolean updateRequest(String _VUserName, DateTime newToDate) 
{ 
    SqlConnection conn = getConnection(); 
    SqlCommand command = new SqlCommand(); 
    command.CommandText = "UPDATE Requests SET [To] = @ToDate FROM Requests INNER JOIN "+ 
        "VUsers ON Requests.UserRef = VUsers.VUserID WHERE (VUsers.VUserName = @VUserName)"; 

    command.Parameters.AddWithValue("@ToDate", newToDate); 
    command.Parameters.AddWithValue("@VUserName", _VUserName); 

    conn.Open(); 
    try 
    { 
     command.ExecuteNonQuery(); 
     return true; 

    } 
    catch (Exception) 
    { 
     return false; 

    } 
    conn.Close(); 
} 

，但它与_COMPlusExceptionCode = -532459699例外

任何帮助，失败了吗？
