因為 Json.net 是有附原始碼的，他也附了單元測試的專案，底下是我額外增加的UnitTest，我的目標就是讓底下的測試可以pass，而且原來的Test 也要都能通過。

 

ValueTypeTest.cs

using System;
using NUnit.Framework;

namespace Newtonsoft.Json.Test {
	[TestFixture]
	public class ValueTypeTest {
		[Test]
		public void NullTest() {			
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject(class="tags" href="/tags/NULL.html" title=null>null);
			class="tags" href="/tags/OBJECT.html" title=object>object obj = JavaScriptConvert.DeserializeObject<Object>(jsonText);			
			Console.WriteLine(jsonText);
			Assert.IsNull(obj);
		}
		[Test]
		public void StringTest() {
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject("hello world");
			class="tags" href="/tags/OBJECT.html" title=object>object obj = JavaScriptConvert.DeserializeObject<class="tags" href="/tags/OBJECT.html" title=object>object>(jsonText);
			Console.WriteLine(jsonText);
			Assert.AreEqual(obj, "hello world");
		}
		[Test]
		public void IntegerTest() {
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject(1234);
			int n = JavaScriptConvert.DeserializeObject<int>(jsonText);
			Console.WriteLine(jsonText);
			Assert.AreEqual(n, 1234);
		}
		[Test]
		public void DateTimeTest() {
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject(new DateTime(2007, 7, 22, 12, 4, 55));
			DateTime dtime = JavaScriptConvert.DeserializeObject<DateTime>(jsonText);
			Console.WriteLine(jsonText);
			Assert.AreEqual(dtime, new DateTime(2007, 7, 22, 12, 4, 55));
		}
		[Test]
		public void BooleanTest() {
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject(true);
			bool bVal = JavaScriptConvert.DeserializeObject<bool>(jsonText);
			Console.WriteLine(jsonText);
			Assert.AreEqual(bVal, true);
			class="tags" href="/tags/STRING.html" title=string>string jsonText2 = JavaScriptConvert.SerializeObject(false);
			bool bVal2 = JavaScriptConvert.DeserializeObject<bool>(jsonText2);
			Console.WriteLine(jsonText2);
			Assert.AreEqual(bVal2, false);
		}
		[Test]
		public void FloatTest() {
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject(12345.68F);
			class="tags" href="/tags/FLOAT.html" title=float>float fVal = JavaScriptConvert.DeserializeObject<class="tags" href="/tags/FLOAT.html" title=float>float>(jsonText);
			Console.WriteLine(jsonText);
			Assert.AreEqual(fVal, 12345.68F);
		}
		[Test]
		public void EnumTest() {
			class="tags" href="/tags/STRING.html" title=string>string jsonText = JavaScriptConvert.SerializeObject(StoreColor.White);
			StoreColor color = JavaScriptConvert.DeserializeObject<StoreColor>(jsonText);
			Console.WriteLine(jsonText);
			Assert.AreEqual(color, StoreColor.White);
		}
	}
}

開始看code後，發現比想像中的簡單，失敗的原因是作者有檢查且擋掉，或許這不是 bug 而是 by design 吧

JsonSerializer.cs, line:406-407

修改前:
if (value == class="tags" href="/tags/NULL.html" title=null>null) 
    throw new ArgumentNullException("value");

修改後:
//if (value == class="tags" href="/tags/NULL.html" title=null>null)
//    throw new ArgumentNullException("value");

JsonWriter.cs, line 104

修改前:
/* Value */{ State.Error, State.Object, State.Error, State.Error, State.Array, State.Array, State.Error, State.Error },

修改後:
/* Value */{ State.Closed, State.Object, State.Error, State.Error, State.Array, State.Array, State.Error, State.Error },
