如何使用 C# 滚动到 WinForms TextBox 中的指定行?
How can I scroll to a specified line in a WinForms TextBox using C#?
谢谢
滚动到选择的方法如下:
Here's how you scroll to the selection:
textBox.ScrollToCaret();
要滚动到指定行,您可以遍历 TextBox.Lines 属性,将它们的长度相加以找到指定行的开头,然后设置 TextBox.SelectionStart 来定位插入符号.
To scroll to a specified line, you could loop through the TextBox.Lines property, total their lengths to find the start of the specified line and then set TextBox.SelectionStart to position the caret.
类似这样的东西(未经测试的代码):
Something along the lines of this (untested code):
int position = 0;
for (int i = 0; i < lineToGoto; i++)
{
position += textBox.Lines[i].Length;
}
textBox.SelectionStart = position;
textBox.ScrollToCaret();
