打印图片框的内容
大家好，
我的 C# WinForms 应用程序中有一个图片框，大小为 800x800。我想使用以下代码打印此图片框的内容，但它根本不执行任何操作（仅显示打印对话框，当我单击对话框中的“打印”时，它也不执行任何操作。出了什么问题？
private void menuFilePrint_Click(object sender, EventArgs e)
{
printDocument.OriginAtMargins = true;
printDocument.DocumentName = "TEST IMAGE PRINTING";
printDialog.Document = printDocument;
printDialog.ShowDialog();
}
private void printDocument_PrintPage(object sender, PrintPageEventArgs e)
{
e.Graphics.DrawImage(curveBox.Image, 0, 0);
}

您没有指示
printDocument打印：printDialog用于设置打印设置。You didn't instruct the
printDocumentto print:the
printDialogis used to set printing settings.如果没有此命令“printDocument1.Print();”什么都行不通。
Without this command "printDocument1.Print();" Nothing will work.
