我使用的是从我的服务器以下JSON对象下面的方法将它转换成C＃的DataTable

using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) 
{ 
    var result = streamReader.ReadToEnd() ; 
    var table = JsonConvert.DeserializeObject<DataTable>(result); 
}

，但它提供了以下错误;

类型的异常“Newtonsoft.Json.JsonSerializationException” 发生Newtonsoft.Json.dll但在用户代码中没有处理

其他信息：数据表读取时意外JSON令牌。预计的StartArray，得到了String。路径''，第1行，位置3784.

有人可以请解释原因吗？

你必须将其转换为对象，匹配json的结构 - 那么你可以映射到一个数据表，如果这实际上是你需要的 – Rick

另外，你可能想要格式化json，所以它在thw问题中更具可读性 – Rick

首先，创建一个类的对象结构：

[JsonObject] 
    public class BankData 
    { 
    [JsonProperty(PropertyName = "Sync_Time")] 
    public string Sync_Time { get; set; } 

    [JsonProperty(PropertyName = "Bank_Code")] 
    public string Bank_Code { get; set; } 

    [JsonProperty(PropertyName = "Bank_Name")] 
    public string Bank_Name { get; set; } 

    [JsonProperty(PropertyName = "Status")] 
    public int Status { get; set; } 
    }

然后创建一个方法来解析您的JSON并将其转换为数组：

var jsonResponse = .....get json from server... 
    var res = JsonConvert.DeserializeObject<BankData[]>(jsonResponse); 
    // res is your array of BankData.... you can use it here...
