[英]Call async Method from a normal method c#
I am trying to call an async method from a normal method.我正在尝试从普通方法调用异步方法。 I have the following two issues here:我在这里有以下两个问题:
Task.Run
in class A to class B's method, JQuery is not receiving the call.当我在 A 类中使用Task.Run
到 B 类的方法时,JQuery 没有收到调用。await
because it throws this error:我无法使用await
因为它会引发此错误:
The await can only be used in an async method await 只能在异步方法中使用
I am not sure what the issue is with respect to the first problem I am having.我不确定我遇到的第一个问题是什么问题。 Secondly, is there a way to use await
when calling classB because it seems to work when I made a call from a different method that is async.其次,有没有办法在调用 classB 时使用await
,因为当我从不同的异步方法进行调用时它似乎可以工作。
public class A :IA
{
public A ()
{
consumer.Received += Received;
}
public void Received(object sender, BasicDeliverEventArgs ea)
{
//get message here and send to classB
Task.Run(() => classB.PingMesssage(Message));
}
}
public class B
{
public async Task PingMesssage(string message)
{
await InvokeClientMethodToAllAsync("callJQueryMethod", "message"); //calling js here
}
}
You can make Received
async and await a call to PingMessage
:您可以使Received
异步并等待对PingMessage
的调用:
public async void Received(object sender, BasicDeliverEventArgs ea) {
await classB.PingMessage(message);
}
