I have a window form that contain a listbox and some richtextboxex. listbox contains some values. When I select any value from listbox, richtextboxex bind with data according to selected value.

I have to highlight some text which is bind to richtextbox when I select a value from listbox, e.g.:

Just a friendly reminder that you have <<OverdueInvCount>> overdue invoice(s), with an overdue balance of <<OverdueInvTotal>>. If you have any questions about the amount you owe, please give us a call and we’ll be happy to discuss it. If you’ve already sent your payment, please disregard this reminder.

All data is coming from database.

I want to highlight <<OverdueInvCount>> and <<OverdueInvTotal>> these words.

一种不强制转换为具有所需功能的新对象的方法是覆盖ListBox DrawItem

void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    var item = listBox1.Items[e.Index] as <Your_Item>;

    e.DrawBackground();
    if (item.fIsTemplate)
    {
        e.Graphics.DrawString(item.Text + "(Default)", new Font("Microsoft Sans Serif", 8, FontStyle.Regular), Brushes.Black, e.Bounds);
    }
    else
    {
        e.Graphics.DrawString(item.Text, new Font("Microsoft Sans Serif", 8, FontStyle.Regular), Brushes.Black, e.Bounds);
    }
    e.DrawFocusRectangle();
}

并将其添加到您的构造函数中（InitializeComponent();调用后）

listBox1.DrawMode = DrawMode.OwnerDrawFixed;
listBox1.DrawItem += new DrawItemEventHandler(listBox1_DrawItem);

像这样的东西应该可以工作（刚刚测试过这个..似乎工作正常）：

int openBrace = richTextBox.Text.IndexOf("<");
while (openBrace > -1) {
    int endBrace = richTextBox.Text.IndexOf(">", openBrace);
    if (endBrace > -1) {
        richTextBox.SelectionStart = openBrace;
        richTextBox.SelectionLength = endBrace - openBrace;
        richTextBox.SelectionColor = Color.Blue;
    }
    openBrace = richTextBox.Text.IndexOf("<", openBrace + 1);
}
