我需要加载一个大文件并在datagrid中显示数据,但有些我不能异步加载文件。
按钮代码:
private async void MILoadLogFile_Click(object sender, RoutedEventArgs e) {
...
await myLogSession.LoadfromFileAsync(oFD.FileName);
}
}
和加载方法
public async Task LoadfromFileAsync(String fileName) {
StreamReader streamReader = new StreamReader(fileName);
String line;
try {
using (streamReader) {
while ((line = await streamReader.ReadLineAsync()) != null) {
...
}
...
}
Console.Out.WriteLine("DOOOOOOOOOOOOONE");
}
} catch (Exception e) {
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);
}
}
}
这一个工作,但它根本不光滑,我无法移动窗口
答案 0 :(得分:0)
请尝试使用此代码:
private async void MILoadLogFile_Click(object sender, RoutedEventArgs e)
{
//...
await Task.Factory.StartNew(async () =>
{
await myLogSession.LoadfromFileAsync(oFD.FileName);
});
}
