progressbar怎么显示复制进度

Posted 2023-04-02

参考技术A 复制过程和Progressbar的显示过程是在两个线程中的。
复制过程是分片复制的，例如文件总大小是100M，那么每次复制1M。
每次复制完成，把当前复制完成的百分比发消息到Progressbar的线程，Progressbar把这个百分比显示出来就好了

C#进度条怎么用 / C#progressBar的用法

参考技术A 创建进度条窗口2、在其他窗口中调用方法ShowProcess(int percent,string message)

复制代码 代码如下:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using Mes.Core;

namespace HCMDoImport

public partial class ProcessBarForm : BaseForm

int processPercent = 0;
string message = "";
public string Message

get return message;
set

message = value;
this.label1.Text = message;


public int ProcessPercent

get return processPercent;
set

processPercent = value;
if (processPercent >= 100)
this.Close();
this.progressBar1.Value = processPercent;



public ProcessBarForm()

InitializeComponent();

/// <summary>
/// 更新进度
/// </summary>
/// <param name="percent">进度,小于等于100</param>
/// <param name="message">消息</param>
public void ShowProcess(int percent,string message)

this.Show();
this.ProcessPercent = percent;
this.Message = message;
this.progressBar1.Refresh();
this.label1.Refresh();

private void ProcessBarForm_Load(object sender, EventArgs e)

this.Cursor = Cursors.WaitCursor;

private void ProcessBarForm_FormClosing(object sender, FormClosingEventArgs e)

this.Cursor = Cursors.Default;
