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("TokenType/t/tValueType/t/tValue");
while (reader.Read())
{
Console.WriteLine(reader.TokenType + "/t/t" + WriteValue(reader.ValueType) + "/t/t" + 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!',{property:'value'}]
这里会打印出:
['JSON!',{property:'value'}].
