Question

我有.NET Web服务，它应该将结果作为JSON返回，但是它将它作为XML返回？这是我的代码。

[WebService(Namespace = "http://tempuri.org/MyService")]
[ScriptService]
public class MyService : System.Web.Services.WebService
{
    [WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json)]
    public List<MyData> GetMyData(string dataFilter, string param)
    {
        if (dataFilter.ToLower() == "filterValue")
            return getData(param);
        return null;
    } 
}
public class MyData
{
    public string id { get; set; }
    public string name { get; set; }
    protected internal MyData() { } 
}

这是web.config

<system.web>
<compilation debug="true" targetFramework="4.0"/>
<httpRuntime/>
<customErrors mode="Off"/>
<webServices>
  <protocols>
    <add name="HttpGet"/>
    <add name="HttpPost"/>
  </protocols>
</webServices>
<pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>

修改 Web服务仅在传递参数中的数字时才能正常工作，但在参数内传递字符时会返回内部服务器错误。我感到困惑：O

尝试此代码可能对您有所帮助。安装 Newtonsoft.Json 包

<强>代码

    public class HelloWorldData
    {
        public String Message;
    }

    [WebMethod]
    public void Select()
    {
        JavaScriptSerializer js = new JavaScriptSerializer();
        Context.Response.Clear();
        Context.Response.ContentType = "application/json";
        HelloWorldData data = new HelloWorldData();
        string sql = "exec YOUR_SP_NAME";
        SqlDataAdapter da = new SqlDataAdapter(sql, System.Configuration.ConfigurationManager.AppSettings["BB_CONSTR"]);
        DataSet ds = new DataSet();
        da.Fill(ds);
        Context.Response.Write(JsonConvert.SerializeObject(ds, Newtonsoft.Json.Formatting.Indented));
    }

.NET WebService返回XML而不是JSON
