一、C#操作json

一、添加Newtonsoft.Json包

在工程上右键——【管理Nuget程序包】
搜索 Newtonsoft.Json 
添加引用

二、引用

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

三、使用

StringBuilder builder = new StringBuilder();
builder.AppendLine("{");
builder.AppendLine("\"key1\":\"value1\",");
builder.AppendLine("\"key2\":\"value2\",");
builder.AppendLine("\"key3\":\"value3\",");
builder.AppendLine("\"key4\":\"value4\",");
builder.AppendLine("\"key5\":\"value5\",");
builder.AppendLine("\"key6\":\"value6\"");
builder.AppendLine("}");

JObject jObject = JObject.Parse(builder.ToString());
foreach (JProperty jProperty in jObject.Properties())
{
    MessageBox.Show("key:" + jProperty.Name + " value:" + jProperty.Value);
    //Console.WriteLine("key:" + jProperty.Name + " value:" + jProperty.Value);
}

//str 表示的json字符串为json对象
JObject jsonObj = JObject.Parse(str);

//str 表示的json字符串为json数组
JArray jarry = JArray.Parse(str);

实践下：

String Result= "[{ 'Status': 0,'PersonId': '32010013171807260000005' },{'Status': 0,'PersonId': '32010013171809090000002'}]";


//JObject jObject = JObject.Parse(builder.ToString());
JArray jarry = JArray.Parse(Result);

foreach (var ss in jarry)  //查找某个字段与值
{
    MessageBox.Show(ss["Status"].ToString());
}
