c# listview columnHeader 双击自动适应宽度

自定义一个变量widthChangingCount

private void olvData_ColumnWidthChanging(object sender, ColumnWidthChangingEventArgs e)

{

widthChangingCount++;

}

private void olvData_ColumnWidthChanged(object sender, ColumnWidthChangedEventArgs e)

{

if (widthChangingCount < 2) {

ListView listview = (ListView)sender;

listview.Columns[e.ColumnIndex].Width = listview.Columns[e.ColumnIndex].Text.Trim().Length*12; //网上说可以通过设置值为-2 实现自适应，但是我没有实现

}

widthChangingCount = 0;

}
