我需要使用jQuery ajax請求在後面的C#代碼中處理後處理值。我可以發送數據,但我不知道如何從C#WebMethod內部檢索它。如何在C#WebMethod中獲取POST數據?

var cliente; 
$.post(
    "../Dados/GetDados.aspx/GetClienteById", 
    { 
     Id: id 
    }, 
    function(dado) { 
     cliente = dado; 
    }); 

和C#代碼:

[WebMethod] 
[ScriptMethod(ResponseFormat = ResponseFormat.Json)] 
public static string GetClienteById() 
{ 
    int PostId = What_can_I_put_here?; 

    string dados = "null"; 

    using (SysContext db = new SysContext()) // I'm using Entity Framework 
    { 
     if (db.Clientes.Count(r => r.Id == PostId) > 0) 
      dados = new JavaScriptSerializer().Serialize(db.Clientes.Where(r => r.Id == PostId).ToList()); 
    } 
    return dados; 
}

添加它作爲一個參數。

[WebMethod] 
[ScriptMethod(ResponseFormat = ResponseFormat.Json)] 
public static string GetClienteById(int id)
