解决方案

你不能在C＃中截取网页的截图：它在服务器，而不是客户端。这意味着主屏幕是Web服务器屏幕而不是客户端浏览器。它可能会像你想要的那样开发，因为两台计算机都是同一台PC，但是当它们相距数千英里时，它在生产中没有任何用处！



您需要查看使用Javascript： Google [ ^

My code as follows

protected void btnCapture_Click(object sender, EventArgs e)
{

Bitmap bitmap = new Bitmap
(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width, System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height);

Graphics graphics = Graphics.FromImage(bitmap as System.Drawing.Image);
graphics.CopyFromScreen(0, 0, 0, 0, bitmap.Size);

bitmap.Save("E:/ScreenShot.bmp",ImageFormat.Bmp);
}


When i run the above code and click the capture button the whole default.aspx page is not displaying.

Im run mode as follows

SNO textbox1
Name textbox2
Age textbox3
ID textbox4
DOB textbox5
Address textbox6
Place textbxo7
State Dropdownlist1
Pincode textbox8
Mobile textbox9
Father Name textbox10
Mother Name textbox11
Permanent Address textbox12

But when i take screen shot in E folder it save as follows

SNO textbox1
Name textbox2
Age textbox3
ID textbox4
DOB textbox5
Address textbox6
Place textbxo7
State Dropdownlist1

The remaining three as follows
Pincode textbox8
Mobile textbox9
Father Name textbox10
Mother Name textbox11
Permanent Address textbox12


The above three is not displaying in E folder the whole screen is not displaying.

From my above code what is the mistake i made please help me.

解决方案

You can't take a screenshot of the web page in C#: it runs on the server, not the client. That means that the Primary Screen is the web server screen not the client browser. It may do something like what you want in development because both computers are the same PC, but it will do nothing useful in production when the are separated by thousands of miles!

You will need to look at using Javascript for this: Google[^]
