你能帮我解决这个问题吗？我有一个 asp.net 应用程序，在这个应用程序中，我使用 Javascript 序列化程序来序列化数据集，然后转换为列表。该代码如下所示。

JavaScriptSerializer json = new JavaScriptSerializer();
strJson = json.Serialize(aclDoc);

但是，在反序列化时，我得到了一个 ArguementException，例如 Invalid Json Primitives 和我的 Json 值。我的 json 值是

[{"Id":"F79BA508-F208-4C37-9904-DBB1DEDE67DB","App_Id":"ScriptFlow","Name":"New form","FriendlyName":"","Read":"Revoke","ReadRule":"a353776f-cbdc-48b7-a15b-4a2316d19b05","Update":"Grant","UpdateRule":"be30c34e-33ec-4c0a-9f09-4fd483f5f1b9","Create":"Revoke","CreateRule":"898dce4d-4709-45b6-8942-d7efb07cbd86","Delete":"Revoke","DeleteRule":"aa14d435-dec8-4ade-ad9b-830ae5ee15d0"}][{"Id":"1","Doc_Id":"858E013C-5775-4FDF-AA1E-2C84053EE39F","Name":"TextBox1","FriendlyName":"TextBox1","Read":"Grant","ReadRule":"0a2e3c0e-ad8f-4f75-9160-cfd9827ac894","Update":"Grant","UpdateRule":"ecad3cf4-104f-44dc-b815-de039f3a0396"},{"Id":"2","Doc_Id":"858E013C-5775-4FDF-AA1E-2C84053EE39F","Name":"TextBox2","FriendlyName":"TextBox2","Read":"Grant","ReadRule":"81e0e9ef-09f7-4c25-a58e-d5fdfbd4c2ba","Update":"Grant","UpdateRule":"2047f662-c881-413b-a1f9-69f15bf667fc"}]

反序列化的代码是：

JavaScriptSerializer json = new JavaScriptSerializer();
lstDoc = json.Deserialize<List<ACLDocument>>(value);
return lstDoc;

其中 lstDoc 是我的班级类型的列表集合

我得到了这样的例外：

Invalid JSON primitive:
{"Id":"1","Doc_Id":"858E013C-5775-4FDF-AA1E-2C84053EE39F","Name":"TextBox1","FriendlyName":"TextBox1","Read":"Grant","ReadRule":"0a2e3c0e-ad8f-4f75-9160-cfd9827ac894","Update":"Grant","UpdateRule":"ecad3cf4-104f-44dc-b815-de039f3a0396"},{"Id":"2","Doc_Id":"858E013C-5775-4FDF-AA1E-2C84053EE39F","Name":"TextBox2","FriendlyName":"TextBox2","Read":"Grant","ReadRule":"81e0e9ef-09f7-4c25-a58e-d5fdfbd4c2ba","Update":"Grant","UpdateRule":"2047f662-c881-413b-a1f9-69f15bf667fc"}].

请帮我解决这个问题。提前致谢

您的输入字符串确实是一个错误的JSON 字符串。您的输入由两个正确的 JSON 字符串组成：

[
    {
        "Id": "F79BA508-F208-4C37-9904-DBB1DEDE67DB",
        "App_Id": "ScriptFlow",
        "Name": "New form",
        "FriendlyName": "",
        "Read": "Revoke",
        "ReadRule": "a353776f-cbdc-48b7-a15b-4a2316d19b05",
        "Update": "Grant",
        "UpdateRule": "be30c34e-33ec-4c0a-9f09-4fd483f5f1b9",
        "Create": "Revoke",
        "CreateRule": "898dce4d-4709-45b6-8942-d7efb07cbd86",
        "Delete": "Revoke",
        "DeleteRule": "aa14d435-dec8-4ade-ad9b-830ae5ee15d0"
    }
]

和

[
    {
        "Id": "1",
        "Doc_Id": "858E013C-5775-4FDF-AA1E-2C84053EE39F",
        "Name": "TextBox1",
        "FriendlyName": "TextBox1",
        "Read": "Grant",
        "ReadRule": "0a2e3c0e-ad8f-4f75-9160-cfd9827ac894",
        "Update": "Grant",
        "UpdateRule": "ecad3cf4-104f-44dc-b815-de039f3a0396"
    },
    {
        "Id": "2",
        "Doc_Id": "858E013C-5775-4FDF-AA1E-2C84053EE39F",
        "Name": "TextBox2",
        "FriendlyName": "TextBox2",
        "Read": "Grant",
        "ReadRule": "81e0e9ef-09f7-4c25-a58e-d5fdfbd4c2ba",
        "Update": "Grant",
        "UpdateRule": "2047f662-c881-413b-a1f9-69f15bf667fc"
    }
]

但您不能连接两个 JSON 字符串。准确地说出您在这种连接后收到的内容，而不是 JSON 字符串。

我建议您在http://www.jsonlint.com/中验证 JSON 字符串。只需剪切并粘贴您需要验证的数据，然后单击“验证”按钮。

直接回答问题，因为大家都认为这是微软论坛，不直接回答。

字符串作为 2 元素数组发送。您忘记了字符串开头的“[”，它表示包含的值是一个数组结构。

在字符串的开头插入“[”，错误应该会消失。

查看 project.json 中是否有任何 // 或注释行删除它为我解决了同样的问题
