示例1: CoerceList

		{
			if (targetType.IsArray)
			{
				return this.CoerceArray(targetType.GetElementType(), value);
			}

			// targetType serializes as a JSON array but is not an array
			// assume is an ICollection / IEnumerable with AddRange, Add,
			// or custom Constructor with which we can populate it

			// many ICollection types take an IEnumerable or ICollection
			// as a constructor argument.  look through constructors for
			// a compatible match.
			ConstructorInfo[] ctors = targetType.GetConstructors();
			ConstructorInfo defaultCtor = null;
			foreach (ConstructorInfo ctor in ctors)
			{
				ParameterInfo[] paramList = ctor.GetParameters();
				if (paramList.Length == 0)
				{
					// save for in case cannot find closer match
					defaultCtor = ctor;
					continue;
				}

				if (paramList.Length == 1 &&
					TypeCoercionUtility.GetTypeInfo(paramList[0].ParameterType).IsAssignableFrom(TypeCoercionUtility.GetTypeInfo(arrayType)))
				{
					try
					{
						// invoke first constructor that can take this value as an argument
						return ctor.Invoke(
								new object[] { value }
							);
					}
					catch
					{
						// there might exist a better match
						continue;
					}
				}
			}

			if (ConstructorInfo.Equals (defaultCtor, null)) {
				throw new JsonTypeCoercionException (
					String.Format (TypeCoercionUtility.ErrorDefaultCtor, new System.Object[] { targetType.FullName }));
			}
			object collection;
			try

				// always try-catch Invoke() to expose real exception
				collection = defaultCtor.Invoke(null);
			}

				{
					throw new JsonTypeCoercionException(ex.InnerException.Message, ex.InnerException);
				}
				throw new JsonTypeCoercionException("Error instantiating " + targetType.FullName, ex);
			}

			// many ICollection types have an AddRange method
			// which adds all items at once
			#if WINDOWS_STORE
			/** \todo Not sure if this finds the correct methods */
			MethodInfo method = TCU.GetTypeInfo(targetType).GetDeclaredMethod("AddRange");

			{
				try

				}
				return collection;
			}
			else
			{
				// many ICollection types have an Add method
