c# - 在函数执行期间将进度条与函数中的值链接
问题描述
我已经创建了一个带有公共函数的类在执行期间返回一个列表公共int在函数结束时增加到100这个进度条的值在函数期间增加如何在类中的公共int和wpf中的进度条之间进行同步最后的形式我想要 sList 作为结果和 WeekListsProgress 作为进度条 vlaue

解决方案

private async void Button_Click(object sender, RoutedEventArgs e)
{
var sl = new List<Sessions>();
var progress = new Progress<int>(value =>
{
pbWeekList.Value =value ;
});
await Task.Run(() => sl= SchedHandler.WeekLists(1, progress));
dg.ItemsSource = sl;
}
但首先你必须改为
public static List<Sessions> WeekLists(int semId,IProgress<int> progress)
{
WeekListsProgress = 0;
progress.Report(WeekListsProgress);
/////////////////////
/////////////////
////////////////
Thread.Sleep(100);
WeekListsProgress = 100;
progress.Report(WeekListsProgress);
return sList;
}
