如何使用C#web客户端传递嵌入式JSON

我需要通过API传递嵌入式JSON文件

public static string EvaluateRating(string jsonFile,string vKey, string mobileNo, string nic)
{
    try
    {
        object input = new
        {
            ErrorMessage = "",
            ErrorStatus = false,
            ValidationDataDetails = new
            {
                SessionID = "Ses21",
                ValidatiorKey = vKey.Replace("\"", "")
            },
            onlineRequestFields = new
            {
                SelectedProduct = 162,
                JsonFile = jsonFile
            },
        };

        string inputJson = (new JavaScriptSerializer()).Serialize(input);
        WebClient webClient = new WebClient();
        WebClient client = webClient;
        client.Headers["Content-type"] = "application/json";
        client.Encoding = Encoding.UTF8;
        string json = client.UploadString(apiUrl + "/EvaluateRating", inputJson);
        return json;
    }
    catch (WebException webEx)
    {
        Console.WriteLine(webEx);
    }
    return null;
}

这里，我将嵌入式JSON作为参数传递

参数

jsonFile

字符串如下所示

{\"evaluation\":{\"numeric\":[{\"@parameter-id\":\"2657\",\"@new-value\":\"\",\"@label\":\"Monthly Income\"},{\"@parameter-id\":\"2614\",\"@new-value\":\"\",\"@label\":\"Existing Financial\"},{\"@parameter-id\":\"2608\",\"@new-value\":\"\",\"@label\":\"Basic Salary\"},{\"@parameter-id\":\"2661\",\"@new-value\":\"\",\"@label\":\"Existig Card\"},{\"@parameter-id\":\"2609\",\"@new-value\":\"\",\"@label\":\"Fixed Allowances\"},{\"@parameter-id\":\"2611\",\"@new-value\":\"\",\"@label\":\"Other Income \"}]}}

传递

JSONFile

后，

inputJson

的值显示如下（运行时的部分值）

这会产生错误，因为API不接受

\\\\

，当我将JsonFile设置为静态时，API返回预期输出，但没有错误

JsonFile = "{\"evaluation\":{\"numeric\":[{\"@parameter-id\":\"2657\",\"@new-value\":\"\",\"@label\":\"Monthly Income\"},{\"@parameter-id\":\"2614\",\"@new-value\":\"\",\"@label\":\"Existing Financial\"},{\"@parameter-id\":\"2608\",\"@new-value\":\"\",\"@label\":\"Basic Salary\"},{\"@parameter-id\":\"2661\",\"@new-value\":\"\",\"@label\":\"Existig Card\"},{\"@parameter-id\":\"2609\",\"@new-value\":\"\",\"@label\":\"Fixed Allowances\"},{\"@parameter-id\":\"2611\",\"@new-value\":\"\",\"@label\":\"Other Income \"}]}}",

我认为在

序列化之后

对象输入变成这样

{\r\n \\\"@parameter-id\\\": \\\"2657\\\",\r\n \\\"@new-value\\\": \\\"\\\",\r\n \\\"@label\\\": \\\"Monthly Income - PersonalAdvances\\\"

那么，如何使用C#

WebClient传递这个嵌入式JSON文件呢

{\r\n \\\"@parameter-id\\\": \\\"2657\\\",\r\n \\\"@new-value\\\": \\\"\\\",\r\n \\\"@label\\\": \\\"Monthly Income - PersonalAdvances\\\"
