怎么使用C# WinForm RichTextBox文本动态滚动显示文本(richtextbox,winform,开发技术)

WinForm RichTextBox文本动态滚动显示文本方

在RichTextBox动态显示一些文本信息时，需要一些设置，显示当前要显示的字符串。

一个RichTextBox，一个按钮。

下图为运行时显示过程中

Form1.cs

usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Text;usingSystem.Windows.Forms;namespaceRichTextBoxScroll{publicpartialclassForm1:Form{privatedelegatevoiddelInfoList(stringtext);publicForm1(){InitializeComponent();}privatevoidSetrichTextBox(stringvalue){if(richTextBox1.InvokeRequired)//其它线程调用{delInfoListd=newdelInfoList(SetrichTextBox);richTextBox1.Invoke(d,value);}else//本线程调用{if(richTextBox1.Lines.Length>100){richTextBox1.Clear();}richTextBox1.Focus();//让文本框获取焦点richTextBox1.Select(richTextBox1.TextLength,0);//设置光标的位置到文本尾richTextBox1.ScrollToCaret();//滚动到控件光标处richTextBox1.AppendText(value);//添加内容}}privatevoidbutton1_Click(objectsender,EventArgse){for(inti=0;i<300;i++){SetrichTextBox(DateTime.Now.ToString()+"内容滚动打印中!!!\n");}}}}
