如何在C#中调用Web API或其他宁静的Web服务 [英] how to call web api or other restful web services in c#

问题描述

我可以通过ajax请求调用每个 webApi 方法，但是用c#无法做到.这是一个简单的Web api，每个人都可以在asp.net mvc Web api中创建它，但是我找不到任何有关调用的示例，并且无法通过c#进行编程获取.

I can call every webApi methods by ajax request but I can't do it by c#. this is a simple web api which every body can create it in asp.net mvc web api but I can't find any example about call and get it programmatically by c#.

  public class TestController : ApiController
{
    // GET: api/Test
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }
}

请有人告诉我如何在C#中调用此Web api方法并获取这2个值.我们如何在c#中从Web服务( RestFull -无参考)中获取价值?

please some body say me how can I call this web api method in c# and get these 2 values. how can we get value from a web service(RestFull-without reference) in c# ?

推荐答案

答案是这样的……所有给出负面反应的人都可以这样做，而不是负面反应:

the answer is this...all persons who give negative reaction can do this instead of negative reactions:

        string GET(string url)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        try
        {
            WebResponse response = request.GetResponse();
            using (Stream responseStream = response.GetResponseStream())
            {
                StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                return reader.ReadToEnd();
            }
        }
        catch (WebException ex)
        {
            WebResponse errorResponse = ex.Response;
            using (Stream responseStream = errorResponse.GetResponseStream())
            {
                StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
                String errorText = reader.ReadToEnd();
                // log errorText
            }
            throw;
        }
    }

那么容易！
