当在服务器中执行以下代码时，它无法正常工作 [英] when execute the below code in server it is not working

问题描述

我的代码如下

Bitmap bitmap = new Bitmap(990, 540);
Graphics graphics = Graphics.FromImage(bitmap as System.Drawing.Image);
graphics.CopyFromScreen(5, 160, 0, 0, bitmap.Size);
bitmap.Save(@"c:\\" + ddlSession.Text.ToString().Trim() + "DailySchedule.bmp", ImageFormat.Bmp);
lblUpdate.Text = "This image is saved";

当我在本地机器上执行上面的代码时，它正在工作，但当我在服务器错误中执行上述代码时，如下所示

System.ComponentModel .Win32Exception：句柄无效 .Error在下面的行显示如下

When i execute the above code in local machine it is working, but when i execute the above code in server error as follows
System.ComponentModel.Win32Exception: The handle is invalid.Error shows in below line as follows

graphics.CopyFromScreen(5, 160, 0, 0, bitmap.Size);

请帮帮我。我的代码有什么问题。
