c# - 从 webservice 返回两个值

Question

可以将两个值从 WebService 返回到 jQuery。

我试过

[WebMethod(EnableSession = true)]
public string testing(string testId)
{
    string data = string.Empty;
    string data1 = string.Empty;
    List<test1> datalist1 = new List<test1>();
    List<test> datalist = new List<test>();

    //coding
    data = jsonSerialize.Serialize(datalist1);
    data1 = jsonSerialize.Serialize(datalist);
    return [data,data1];
}

但它显示错误....我们如何从此处的 webservice 返回两个值......

Answer 1

另一种方法是创建一个具有您想要的两个返回值的自定义数据类型:

[Serializable]
public sealed class MyData
{
    public string Data { get; set; }
    public string Data1 { get; set; }
}

...

[WebMethod(EnableSession = true)]
public MyData testing(string testId)
{
    string data = string.Empty;
    string data1 = string.Empty;
    List<test1> datalist1 = new List<test1>();
    List<test> datalist = new List<test>();

    //coding
    data = jsonSerialize.Serialize(datalist1);
    data1 = jsonSerialize.Serialize(datalist);
    return new MyData { Data = data, Data1 = data1 };
}

或

[Serializable]
public sealed class MyData
{
    public List<test> Data { get; set; }
    public List<test1> Data1 { get; set; }
}

...

[WebMethod(EnableSession = true)]
public string testing(string testId)
{
    MyData data = new MyData();
    string alldata = string.Empty;
    List<test1> datalist1 = new List<test1>();
    List<test> datalist = new List<test>();

    //coding
    data.Data = datalist1;
    data.Data1 = datalist;
    alldata = jsonSerialize.Serialize(data);
    return alldata;
}
