我们有这样的方法:
async Task<int> AccessTheWebAsync()
{
HttpClient client = new HttpClient();
Task<string> getStringTask = client.GetStringAsync("http://msdn.microsoft.com");
// You can do work here that doesn't rely on the string from GetStringAsync.
DoIndependentWork();
string urlContents = await getStringTask;
//The thing is that this returns an int to a method that has a return type of Task<int>
return urlContents.Length;
}
隐式转换是否发生在Task<int>
和int
之间?如果没有,那么发生了什么?它是如何实现的?
