Question

我真的试图自己解决我的问题。我想反序列化一个JSON文件。我建立了一个非常基本的程序，只是为了看它是否有效。我认为我的班级定义可能不正确。

以下是显示反序列化结果的程序部分：

string json = txtJSON.Text;
Class1.Vartable xxx = new Class1.Vartable();

Newtonsoft.Json.JsonConvert.PopulateObject(json, xxx);
MessageBox.Show(xxx.addr);

我的班级定义如下：

public class Rootobject
{
    public Class1[] Property1 { get; set; }
}

public class Class1
{
    //....
    public Vartable[] vartable { get; set; }
    //....

    public class Vartable
    {
        public string addr { get; set; }
        public string name { get; set; }
    }
}

还有很多，但这应该是有趣的部分。

最后但并非最不重要的是我的json文件：

如果我粘贴完整的JSON文件我的程序sy它无效，导致第一个和最后一个[括号]。

如果我只是使用这个＆＃34; {＆＃34; addr＆＃34;：＆＃34; DB4，INT2＆＃34;，＆＃34; name＆＃34;：＆＃34; Value_1＆＃34; }＆＃34;它工作正常。

提前谢谢。

JSON反序列化不能使用Newtonsoft.JSON
