根据我的理解，你想将光标的位置设置在

a TextBox中，就在第一个字符之前文本。

Based on my understanding, you'd like to set the position of the cursor in
a TextBox to just before the first character of the text.

以下是示例代码。它要求你在

表格上添加一个TextBox。

The following is a sample code. It requires that you add a TextBox on a
form.

private void Form1_Load(object sender, EventArgs e)
{
this.textBox1.Text = "hell world text testing cursor pointer ...";

this.textBox1.SelectionStart = 0;
}

或



检查



具有搜索行编号，项目符号，打印，搜索支持的RichTextBox [ ^ ]



问候，

Check it

RichTextBox with Search Line Numbering, Bulleting, Printing, Searching Support[^]

int position = 0;
public void GotoLine(int LineNum)       // Go to line num...
{
    position = 0;

    for (int i = 1; i <= LineNum; i++)
    FindNext("\n");
}

public void FindNext(string FindValue)      // Find word...
{
    int start = this.TextBox1.Text.IndexOf(FindValue, position);
    int length = FindValue.Length;

    this.TextBox1.Select(start, length);

    position = start + length;
}
