示例1: InstantiateObject
internal Object InstantiateObject(Type objectType, out Dictionary<string, MemberInfo> memberMap)
{
if (objectType.IsInterface || objectType.IsAbstract || objectType.IsValueType)
{
throw new JsonTypeCoercionException(
String.Format(TypeCoercionUtility.ErrorCannotInstantiate, objectType.FullName));
}
ConstructorInfo ctor = objectType.GetConstructor(Type.EmptyTypes);
if (ctor == null)
{
throw new JsonTypeCoercionException(
String.Format(TypeCoercionUtility.ErrorDefaultCtor, objectType.FullName));
}
Object result;
try
{
// always try-catch Invoke() to expose real exception
result = ctor.Invoke(null);
}
catch (TargetInvocationException ex)
{
if (ex.InnerException != null)
{
throw new JsonTypeCoercionException(ex.InnerException.Message, ex.InnerException);
}
throw new JsonTypeCoercionException("Error instantiating " + objectType.FullName, ex);
}
memberMap = GetMemberMap (objectType);
return result;
}示例2: GetConstructor
public static ConstructorInfo GetConstructor (Type type, ConstructorInfo constructor)
{
/*FIXME I would expect the same checks of GetMethod here*/
if (type == null)
throw new ArgumentException ("Type is not generic", "type");
if (!type.IsGenericType)
throw new ArgumentException ("Type is not a generic type", "type");
if (type.IsGenericTypeDefinition)
throw new ArgumentException ("Type cannot be a generic type definition", "type");
if (constructor == null)
throw new NullReferenceException (); //MS raises this instead of an ArgumentNullException
if (!constructor.DeclaringType.IsGenericTypeDefinition)
throw new ArgumentException ("constructor declaring type is not a generic type definition", "constructor");
if (constructor.DeclaringType != type.GetGenericTypeDefinition ())
throw new ArgumentException ("constructor declaring type is not the generic type definition of type", "constructor");
ConstructorInfo res = type.GetConstructor (constructor);
if (res == null)
throw new ArgumentException ("constructor not found");
return res;
}
