在windows項目中調用asp.net webmethod

Question

如何從Windows應用程序調用ASP.NET中的這個WebMethod？

我試過使用web請求發佈方法，但它返回的是ASP.NET頁面的XML。

這裏是我的Web方法：

[WebMethod()] 
public static string Senddata(string value) 
{ 
    return "datareceived" + value; 
}

試試這個：

var theWebRequest = HttpWebRequest.Create("http://YOURURL/YOURPAGE.aspx/Senddata"); 
theWebRequest.Method = "POST"; 
theWebRequest.ContentType = "application/json; charset=utf-8"; 
theWebRequest.Headers.Add(HttpRequestHeader.Pragma, "no-cache"); 

using (var writer = theWebRequest.GetRequestStream()) 
{ 
    string send = null; 
    send = "{\"value\":\"test\"}"; 

    var data = Encoding.ASCII.GetBytes(send); 

    writer.Write(data, 0, data.Length); 
} 

var theWebResponse = (HttpWebResponse)theWebRequest.GetResponse(); 
var theResponseStream = new StreamReader(theWebResponse.GetResponseStream()); 

string result = theResponseStream.ReadToEnd(); 

// Do something with the result 
TextBox1.Text = result; 

注意：您需要用實際值替換YOURURL和YOURPAGE。
