对于已经有的组件，可以直接添加进来，添加后要先运行一下，然后会在工具箱内找到相应控件。

1、首先编写组件，然后将组件添加到工具箱内

编写代码如下：

public partial class ListViewEx : System.Windows.Forms.ListView { public ListViewEx() { InitializeComponent(); } //C# listview进度条显示 private Color mProgressColor = Color.Red; public Color ProgressColor { get { return this.mProgressColor; } set { this.mProgressColor = value; } } private Color mProgressTextColor = Color.Black; public Color ProgressTextColor { get { return mProgressTextColor; } set { mProgressTextColor = value; } } public int ProgressColumIndex { set { progressIndex = value; } get { return progressIndex; } } int progressIndex = -1; const string numberstring = "0123456789."; private bool CheckIsFloat(String s) { //C# listview进度条显示 foreach (char c in s) { if (numberstring.IndexOf(c) > -1) { continue; } else return false; } return true; } protected override void Dispose(bool disposing) { base.Dispose(disposing); } //C# listview进度条显示 private void InitializeComponent() { this.OwnerDraw = true; this.View = View.Details; } protected override void OnDrawColumnHeader(DrawListViewColumnHeaderEventArgs e) { e.DrawDefault = true; base.OnDrawColumnHeader(e); } protected override void OnDrawSubItem(DrawListViewSubItemEventArgs e) { if (e.ColumnIndex != this.progressIndex) { e.DrawDefault = true; base.OnDrawSubItem(e); } else { if (CheckIsFloat(e.Item.SubItems[e.ColumnIndex].Text)) //判断当前subitem文本是否可以转为浮点数 { float per = float.Parse(e.Item.SubItems[e.ColumnIndex].Text); if (per >= 1.0f) { per = per / 100.0f; } Rectangle rect = new Rectangle(e.Bounds.X, e.Bounds.Y, e.Bounds.Width, e.Bounds.Height); DrawProgress(rect, per, e.Graphics); } } } //C# listview进度条显示 ///绘制进度条列的subitem private void DrawProgress(Rectangle rect, float percent, Graphics g) { if (rect.Height > 2 && rect.Width > 2) { if ((rect.Top > 0 && rect.Top < this.Height) && (rect.Left > this.Left && rect.Left < this.Width)) { //绘制进度 int width = (int)(rect.Width * percent); Rectangle newRect = new Rectangle(rect.Left + 1, rect.Top + 1, width - 2, rect.Height - 2); using (Brush tmpb = new SolidBrush(this.mProgressColor)) { g.FillRectangle(tmpb, newRect); } newRect = new Rectangle(rect.Left + 1, rect.Top + 1, rect.Width - 2, rect.Height - 2); g.DrawRectangle(Pens.RoyalBlue, newRect); StringFormat sf = new StringFormat(); sf.Alignment = StringAlignment.Center; sf.LineAlignment = StringAlignment.Center; sf.Trimming = StringTrimming.EllipsisCharacter; newRect = new Rectangle(rect.Left + 1, rect.Top + 1, rect.Width - 2, rect.Height - 2); using (Brush b = new SolidBrush(mProgressTextColor)) { g.DrawString(percent.ToString("p1"), this.Font, b, newRect, sf); } } } //C# listview进度条显示 else { return; } } }

2、调用方法：

private void Form1_Load(object sender, EventArgs e) { ListViewItem lviUserName = new ListViewItem(); ListViewItem.ListViewSubItem lvsinc = new ListViewItem.ListViewSubItem(); ListViewItem.ListViewSubItem lvsihostname = new ListViewItem.ListViewSubItem(); ListViewItem.ListViewSubItem lvsiip = new ListViewItem.ListViewSubItem(); lviUserName.Text = "5"; lvsinc.Text = "4"; lvsihostname.Text = "3"; lvsiip.Text = "100"; lviUserName.SubItems.Add(lvsinc); lviUserName.SubItems.Add(lvsihostname); lviUserName.SubItems.Add(lvsiip); this.listView1.Items.Add(lviUserName); this.listView1.ProgressTextColor = Color.Red; this.listView1.ProgressColor = Color.YellowGreen; } private void listView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e) { //设置进度条的ColunIndex this.listView1.ProgressColumIndex = 1; } private void timer1_Tick(object sender, EventArgs e) { if (Convert.ToInt32(listView1.Items[0].SubItems[1].Text.ToString()) <= 100) { //进度条数字更新 listView1.Items[0].SubItems[1].Text = (Convert.ToInt32(listView1.Items[0].SubItems[1].Text.ToString()) + 1).ToString(); } }

3、注意要添加Timer控件

相应属性设置如下：

4、运行结果如下所示

以上所述是基于C#实现带进度条的ListView ，希望对大家有所帮助。
