我创建了 RichTextBox 并添加了以下代码:
private void richTextBox1_TextChanged(object sender, EventArgs e)
{
//( )
int selectionStart = richTextBox1.SelectionStart;
string helpText = richTextBox1.Text;
int closerPos;
for (int i = 0; i < helpText.Length; i++)
{
if (helpText[i] == '(')
{
selectionStart = richTextBox1.SelectionStart;
closerPos = helpText.Substring(i).IndexOf(')') + i;
helpText = helpText.Substring(i + 1, closerPos - i - 1);
richTextBox1.Text = richTextBox1.Text.Remove(i + 1, closerPos - i - 1);
richTextBox1.Select(i + 1, 0);
richTextBox1.SelectionColor = Color.Red;
richTextBox1.SelectedText = helpText;
richTextBox1.SelectionColor = Color.Black;
helpText = richTextBox1.Text;
richTextBox1.SelectionStart = selectionStart;
}
}
}
此代码应为 ( ) 之间的文本着色。例如:
“嗨(需要着色)文本(sdadsasd)”
( ) 之间的文本需要用红色着色。但只有最后一个文本是彩色的。我该如何解决?
