c# - 异步 : What practices in large classes?

Question

让大类完全异步兼容是个好主意还是应该使用其他方法？

理解示例:

AsyncValidateUserInput.cs

public async Task<TaskStateHelper> CheckSiteIsReachable()
public async Task<TaskStateHelper> VerifyCertificate()
public async Task<TaskStateHelper> TestAccount()
{
    #DoStuff
    await exchangeAccount.FetchAccountInformation
    #DoStuff
    await exchangeAccount.GetAccountBalance
    #DoStuff
}

GetAccountBalance 基于 AccountManager 类:

AccountManager.cs

public async Task<decimal> GetAccountBalance()
{
    #DoStuff
    await FooAPI.GetAccountBalanceAsync()
}

FooAPI.cs

public async Task<Dictionary<string, decimal>> GetAccountBalanceAsync()
{
    var queryResult = await QueryPrivateAsync("Balance");
    #DoStuff
}

private async Task<Stream> QueryPrivateAsync(string method, Dictionary<string, string> param = null)
{
    #DoStuff
    await postStream.WriteAsync(postData);
    #DoStuff
    await ReadFromStreamAsync(webResponse.GetResponseStream());
    #DoStuff
}

另一种方法是简单地创建一个任务。

result = await Task.Factory.StartNew(exchangeAccount.GetAccountBalance);

我使用的异步规则兼容吗？

谢谢你的时间

是的，无论大小如何，制作任何应该是 Async 的东西通常是个好主意。本文可能有所帮助:https://msdn.microsoft.com/en-us/magazine/jj991977.aspx
