C# Winform进度条显示
BoomBiuBiu 人气:0创建一个窗体,命名为StartForm
添加一个timer控件并更改名字为timerStart
添加一个ProgressBar控件,并调整一下属性:
StartForm窗体的代码:
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; namespace MVtest { public partial class StartForm : Form { public StartForm() { InitializeComponent(); } //修饰符 delegate 返回值类型 委托名 ( 参数列表 ); private delegate void TIMEinvoke(int val); //委托显示客户端列表 private void DataDisplay(int val) { if(this.InvokeRequired) { TIMEinvoke myIvoke = new TIMEinvoke(DataDisplay); this.Invoke(myIvoke,new object[] { val }); } else { this.PBress.Value = val; } } //事件 int times = 0; private void timerStart_Tick(object sender, EventArgs e) { times++; DataDisplay(times); if(times>=20) { PBress.Visible=false; //关闭timer控件 timerStart.Enabled=false; this.Close(); } } //窗体加载 private void StartForm_Load(object sender, EventArgs e) { timerStart.Interval = 100; timerStart.Enabled=true; PBress.Visible=true; PBress.Maximum = 32; } } }
在Program.cs里面加入代码:
namespace MVtest { internal static class Program { /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new StartForm()); Application.Run(new MainForm()); } } }
