System.Windows.Forms.RichTextBox 已得到类型的属性颜色名称 selectionColor设置它获取或设置当前选择或插入点的文字颜色。您可以使用此属性来标记你的的RichTextBox 具体领域与您指定的颜色。

System.Windows.Forms.RichTextBox has got a property of type Color of the name SelectionColor which gets or sets the text color of the current selection or insertion point. You can use this property to mark specific fields in your RichTextBox with the colors you specify.

示例

_RichTextBox.Select(0, 8); //Select text within 0 and 8
_RichTextBox.SelectionColor = Color.Red; //Set the selected text color to Red
_RichTextBox.Select(8, 16); //Select text within 8 and 16
_RichTextBox.SelectionColor = Color.Green; //Set the selected text color to Green
_RichTextBox.Select(0,0); //Select text within 0 and 0

请注意：您可以避开计算使用 RichTextBox.Find（字符串str）可以通过添加对象浏览器如果你想突出的的RichTextBox 的行中的文本给它的值

Notice that: You may avoid calculations by using RichTextBox.Find(string str) which can be added through Object Browser if you would like to highlight the text within the Lines in RichTextBox giving it's value

_RichTextBox.Find("Account 12345, deposit 100$, balance 200$"); //Find the text provided
_RichTextBox.SelectionColor = Color.Green; //Set the selected text color to Green
