解决方案
Newtonsoft.Json序列化和反序列
这里下载:http://www.newtonsoft.com/products/json/
安装:
1.解压下载文件,得到Newtonsoft.Json.dll
2.在项目中添加引用..
序列化和反序列在.net项目中:
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
string output = javascriptConvert.SerializeObject(product);
//{
// "Name": "Apple",
// "Expiry": new Date(1230422400000),
// "Price": 3.99,
// "Sizes": [
// "Small",
// "Medium",
// "Large"
// ]
//}
Product deserializedProduct = (Product)javascriptConvert.DeserializeObject(output, typeof(Product));
读取JSON
string jsonText = "['JSON!',1,true,{property:'value'}]";
JsonReader reader = new JsonReader(new StringReader(jsonText));
Console.WriteLine("TokenTypettValueTypettValue");
while (reader.Read())
{
Console.WriteLine(reader.TokenType + "tt" + WriteValue(reader.ValueType) + "tt" + WriteValue(reader.Value))
}
结果显示:
TokenType ValueType Value
StartArray null null
String System.String JSON!
Integer System.Int32 1
Boolean System.Boolean True
StartObject null null
PropertyName System.String property
String System.String value
EndObject null null
EndArray null null
JSON写入
StringWriter sw = new StringWriter();
JsonWriter writer = new JsonWriter(sw);
writer.WriteStartArray();
writer.WriteValue("JSON!");
writer.WriteValue(1);
writer.WriteValue(true);
writer.WriteStartObject();
writer.WritePropertyName("property");
writer.WriteValue("value");
writer.WriteEndObject();
writer.WriteEndArray();
writer.Flush();
string jsonText = sw.GetStringBuilder().ToString();
Console.WriteLine(jsonText);
// ['JSON!',1,true,{property:'value'}]
这里会打印出: ['JSON!',1,true,{property:'value'}].
