示例1: CoerceList

		private object CoerceList(Type targetType, Type arrayType, IEnumerable value)
		{
			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 &&
					paramList[0].ParameterType.IsAssignableFrom(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 (defaultCtor == null)
			{
				throw new JsonTypeCoercionException(
					String.Format(TypeCoercionUtility.ErrorDefaultCtor, targetType.FullName));
			}
			object collection;
			try
			{
				// always try-catch Invoke() to expose real exception
				collection = defaultCtor.Invoke(null);
			}
			catch (TargetInvocationException ex)
			{
				if (ex.InnerException != 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
			MethodInfo method = targetType.GetMethod("AddRange");
			ParameterInfo[] parameters = (method == null) ?
					null : method.GetParameters();
			Type paramType = (parameters == null || parameters.Length != 1) ?
					null : parameters[0].ParameterType;
			if (paramType != null &&
				paramType.IsAssignableFrom(arrayType))
			{
				try
				{
					// always try-catch Invoke() to expose real exception
					// add all members in one method
					method.Invoke(
						collection,
						new object[] { value });
				}
				catch (TargetInvocationException ex)
				{
					if (ex.InnerException != null)
					{
						throw new JsonTypeCoercionException(ex.InnerException.Message, ex.InnerException);
					}
					throw new JsonTypeCoercionException("Error calling AddRange on " + targetType.FullName, ex);
				}
				return collection;
			}
			else
			{
				// many ICollection types have an Add method
				// which adds items one at a time
				method = targetType.GetMethod("Add");
				parameters = (method == null) ?
						null : method.GetParameters();
				paramType = (parameters == null || parameters.Length != 1) ?

示例2: GetMethod

		public static MethodInfo GetMethod (Type type, MethodInfo method)
		{
			if (!IsValidGetMethodType (type))
				throw new ArgumentException ("type is not TypeBuilder but " + type.GetType (), "type");

			if (type is TypeBuilder && type.ContainsGenericParameters)
				type = type.MakeGenericType (type.GetGenericArguments ());

			if (!type.IsGenericType)
				throw new ArgumentException ("type is not a generic type", "type");

			if (!method.DeclaringType.IsGenericTypeDefinition)
				throw new ArgumentException ("method declaring type is not a generic type definition", "method");
			if (method.DeclaringType != type.GetGenericTypeDefinition ())
				throw new ArgumentException ("method declaring type is not the generic type definition of type", "method");
			if (method == null)
				throw new NullReferenceException (); //MS raises this instead of an ArgumentNullException

			MethodInfo res = type.GetMethod (method);
			if (res == null)
				throw new ArgumentException (String.Format ("method {0} not found in type {1}", method.Name, type));
				
			return res;
		}
