本文实例为大家分享了c#实现qq聊天窗口的具体代码，供大家参考，具体内容如下

效果图：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.linq;
using system.text;
using system.threading.tasks;
using system.windows.forms;
using system.threading;// 用于暂停 的线程
namespace 聊天窗口
{
    public partial class form1 : form
    {
        public form1()
        {
            initializecomponent();
        }

        int x, y;// x为窗体left，y为窗体top
        private void form1_load(object sender, eventargs e)
        {
            this.location = new point(screen.primaryscreen.workingarea.width / 2 - this.width / 2, screen.primaryscreen.workingarea.height / 2 - this.height / 2);
            x = this.left;
            y = this.top;
            this.acceptbutton = button2; //按回车发送
            textbox1.readonly = true; // 禁止输入
            textbox1.scrollbars = scrollbars.vertical; //显示垂直滚动条
            textbox1.font = new font("", 16);
            textbox2.font = new font("", 16); 
        }
        int t = 5, space = 10;// t为暂停时间，space为移动距离

        //抖动
        private void button1_click(object sender, eventargs e)
        {  // 循环抖动
            for (int i = 0; i <5; i++)
            {  // 改变窗体位置
                this.location = new point(x - space, y);
                thread.sleep(t);
                this.location = new point(x - space, y - space);
                thread.sleep(t);
                this.location = new point(x, y - space);
                thread.sleep(t);
                this.location = new point(x + space, y - space);
                thread.sleep(t);
                this.location = new point(x + space, y);
                thread.sleep(t);
                this.location = new point(x + space, y + space);
                thread.sleep(t);
                this.location = new point(x, y + space);
                thread.sleep(t);
                this.location = new point(x - space, y + space);
                thread.sleep(t);
                this.location = new point(x - space, y);
                thread.sleep(t);
                this.location = new point(x, y);
            }
        }
        // 发送
        private void button2_click(object sender, eventargs e)
        { 
            // 记录超出文本框高度 最新消息显示
            textbox1.appendtext(datetime.now + "\r\n" + textbox2.text + "\r\n");
            textbox2.text = " ";// 文本框清空
        }

    }
}
