How to utilize the print dialog control in WinForm?

Here are the steps to utilize the print dialog control in WinForm:

1. Open your WinForm application project in Visual Studio.
2. Place a button control on the form to trigger the print dialog.
3. Double click on the button control to open the button’s click event handler.
4. Add the following code in the button’s click event handler.

PrintDialog printDialog = new PrintDialog();
if (printDialog.ShowDialog() == DialogResult.OK)
{
    // 打印代码
}

1. In the above code, a PrintDialog object is first created and the Print dialog is then displayed using the ShowDialog method. If the user clicks the “OK” button, DialogResult.OK will be returned.
2. In an if statement, you can include actual printing code. This is just an example, the actual printing code will depend on your needs. You can use the PrintDocument class to implement printing functionality.

In this way, when the user clicks the button, a print dialog box will appear where the user can choose the printer and other print options, and then click the “OK” button to proceed with the printing operation.
