Answer 1

请改用RichTextBox!

    this.myRichTextBox.SelectionStart = 0;
    this.myRichTextBox.SelectionLength = this.contactsTextBox.Text.Length-1;
    myRichTextBox.SelectionFont = new Font(myRichTextBox.SelectionFont, FontStyle.Underline);
    this.myRichTextBox.SelectionLength = 0;

如果你想使用富文本框显示文本，你可以这样做：

richTextBox1.SelectionFont = new Font("Times New Roman", 10, FontStyle.Underline);
richTextBox1.SelectedText = "Message:";
richTextBox1.SelectionFont = new Font("Times New Roman", 10, FontStyle.Regular);
richTextBox1.SelectedText = " This is a message for Name of Client.";

或者，如果消息是动态的并且标题和文本始终用冒号分隔，您可以执行以下操作：

string message = "Message: This is a message for Name of Client";
string[] parts = message.Split(':');
richTextBox1.SelectionFont = new Font("Times New Roman", 10, FontStyle.Underline);
richTextBox1.SelectedText = parts[0] + ":";
richTextBox1.SelectionFont = new Font("Times New Roman", 10, FontStyle.Regular);
richTextBox1.SelectedText = parts[1];

或者，如果您想在标签中动态显示文本，您可以执行以下操作：

string message = "Message: This is a message for Name of Client";
string[] parts = message.Split(':');

Label heading = new Label();
heading.Text = parts[0] + ":";
heading.Font= new Font("Times New Roman", 10, FontStyle.Underline);
heading.AutoSize = true;
flowLayoutPanel1.Controls.Add(heading);

Label message = new Label();
message.Text = parts[1];
message.Font = new Font("Times New Roman", 10, FontStyle.Regular);
message.AutoSize = true;
flowLayoutPanel1.Controls.Add(message);
