ABP AsyncHelper.RunSync 内部实现
using System;
using System.Reflection;
using System.Threading.Tasks;
using Nito.AsyncEx;
namespace Abp.Threading
{
/// <summary>

[Obsolete("Use MethodInfo.IsAsync() extension method!")]
public static bool IsAsyncMethod(MethodInfo method)

return method.IsAsync();

return AsyncContext.Run(func);

/// <param name="action">An async action</param>
public static void RunSync(Func<Task> action)

}
}
}
这是 AsyncHelper 的全部代码,可以看到其实内部就是封装的 Nito.AsyncEx 其他什么都没做。
调用方式:AsyncHelper.RunSync(() => 方法名());
