如何在c＃中正确实现等待异步

How to proper implement await async in c#

本问题已经有最佳答案，请猛点这里访问。

我是新来的C和我正在尝试使用C中的Async和Wait函数来处理线程和非阻塞GUI。

这就是我目前为止所拥有的：

public async Task ReadInfo()
{
string serial;
android.UpdateDeviceList();
if (android.HasConnectedDevices)
{
serial = android.ConnectedDevices[0];
device = android.GetConnectedDevice(serial);
string model = device.BuildProp.GetProp("ro.product.model");
string bootloader = device.BuildProp.GetProp("ro.bootloader");
string pda = device.BuildProp.GetProp("ro.build.PDA");

addlog("Model :" , Color.White, true, true);
addlog(model, Color.DodgerBlue, true, false);
addlog("Bootloader :", Color.White, true, true);
addlog(bootloader, Color.DodgerBlue, true, false);
addlog("PDA Version :", Color.White, true, true);
addlog(pda, Color.DodgerBlue, true, false);
}
else
{
addlog("ADB device not found.", Color.Red, true, true);
}

}

这是addlog方法：

public void addlog(string s, Color color, bool isBold, bool newline = false)
{
if (newline)
{
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.AppendText("

")));
}
Color selectionColor = color;
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.SelectionStart = rtbLog.Text.Length));
rtbLog.BeginInvoke(new MethodInvoker(() => selectionColor = rtbLog.SelectionColor));
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.SelectionColor = color));
if (isBold)
{
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.SelectionFont = new Font(rtbLog.Font, FontStyle.Bold)));
}
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.AppendText(s)));
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.SelectionColor = selectionColor));
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.SelectionFont = new Font(rtbLog.Font, FontStyle.Regular)));
rtbLog.BeginInvoke(new MethodInvoker(() => rtbLog.ScrollToCaret()));
}

在按钮1上单击"我有：

private async void Button1_Click(object sender, EventArgs e)
{
await ReadInfo();
}

我不知道为什么它会冻结图形用户界面。

Solution to the problem

改变

1	public async Task ReadInfo()

到

1	public void ReadInfo()

并调用按钮1单击为

1	Task.Run(() => ReadInfo());
