http calls webservice to operate on the httprequest httpresponse example

REST WCF makes it easy to call Web services through HttpRequest interactions. So can the old WebService do it? In WebService, HttpContext. Current. Rquest/Response, we can also transform WebMethod with one sample.

Client:

//  create 1 a DataTable   
DataTable data = new DataTable("Project");  
data.Columns.Add("Name");  
data.Columns.Add("Birthday");  
data.Rows.Add(new object[] { "Wendy", "1978/03/11" });  
data.Rows.Add(new object[] { "Philip", "2000/11/05" });  
data.Rows.Add(new object[] { "Felix", "1999/08/04" });  
using (var ms = new MemoryStream())  
{  
    //  will DataTable with Xml Format write to stream    
    data.WriteXml(ms, XmlWriteMode.WriteSchema);  
    var client = new WebClient();  
    //  define HttpRequest the Content-Type(xml,json Etc. )   
    client.Headers.Add("Content-Type", "text/xml");  
    var url = "http://localhost:2609/Service1.asmx/SendXml";  
    // Send HttpRequest   
    var resp = client.UploadData(url, "POST", ms.ToArray());  
    var strResp = System.Text.Encoding.UTF8.GetString(resp);  
    MessageBox.Show(strResp);  
}

Server:

[WebMethod]  
public void SendXml()  
{  
    //  Get the client RAW HttpRequest   
    var inputStream = HttpContext.Current.Request.InputStream;  
    //  define Response The format returned is :Json   
    var response = HttpContext.Current.Response;  
    response.ContentType = "text/json";  
    //var strXml = "";   
    //using (var sr = new StreamReader(inputStream))   
    //    strXml = sr.ReadToEnd();   
    try  
    {  
        DataTable data = new DataTable();  
        using (var xr = XmlReader.Create(inputStream))  
            data.ReadXml(xr);  
        //  Will be read in Xml the DataTable The number of rows returned to the client    
        string count = "/"" + data.Rows.Count + "/"";  
        response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(count));  
    }  
    catch (Exception ex)  
    {  
        response.BinaryWrite(System.Text.Encoding.UTF8.GetBytes(ex.Message));  
    }  
}

Client output ""3""

PS: If the client's HttpRequest satisfies the SOAP serialization format, WebService deserializes the message into a parameter for WebMethod. The corresponding client proxy class is also used by the client by deserializing messages into objects.
