我通过反射检查对象的属性,并继续处理每个属性的数据类型。以下是我的(精简)源代码:
private void ExamineObject(object o)
{
Type type = default(Type);
Type propertyType = default(Type);
PropertyInfo[] propertyInfo = null;
type = o.GetType();
propertyInfo = type.GetProperties(BindingFlags.GetProperty |
BindingFlags.Public |
BindingFlags.NonPublic |
BindingFlags.Instance);
// Loop over all properties
for (int propertyInfoIndex = 0; propertyInfoIndex <= propertyInfo.Length - 1; propertyInfoIndex++)
{
propertyType = propertyInfo[propertyInfoIndex].PropertyType;
}
}
我的问题是,我最近需要处理可空属性,但我不知道如何获取可空属性的类型。

可能的解决方案:
propertyType = propertyInfo[propertyInfoIndex].PropertyType;
if (propertyType.IsGenericType &&
propertyType.GetGenericTypeDefinition() == typeof(Nullable<>))
{
propertyType = propertyType.GetGenericArguments()[0];
}

Nullable.GetUnderlyingType(fi.FieldType)
将为你做这些工作,检查下面的代码来做你想做的事情
System.Reflection.FieldInfo[] fieldsInfos = typeof(NullWeAre).GetFields();
foreach (System.Reflection.FieldInfo fi in fieldsInfos)
{
if (fi.FieldType.IsGenericType
&& fi.FieldType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
{
// We are dealing with a generic type that is nullable
Console.WriteLine("Name: {0}, Type: {1}", fi.Name, Nullable.GetUnderlyingType(fi.FieldType));
}
}

foreach (var info in typeof(T).GetProperties())
{
var type = info.PropertyType;
var underlyingType = Nullable.GetUnderlyingType(type);
var returnType = underlyingType ?? type;
}
