I have three lists something like List<EmpRoles> , List<EmpVisibility> , List<EmpProps>.
Now I want to perform certain operations on them. For this first I have to check whether the property is of type list or not. I have use if block something like below
if ( propertyName == "EmpRoles" || propertyName == "EmpVis" || propertyName == "EmpProps")
Is there any better way of doing this thing , or is it possible to put some typeof(list<>) conditions. I know typeof(list<>) won't work here. Either i have to use typeof(list)... Can Someone help in making a generic way to identify the list type properties?

Checking that a type is a List<T> requires ensuring that:
IsGenericType property,System.List<> by checking the result of GetGenericTypeDefinition() against typeof(List<>)T is the one you want by checking GetGenericArguments()If all three conditions are met, you have your type:
var pt = myProperty.PropertyType;
if (pt.IsGenericType &&
pt.GetGenericTypeDefinition() == typeof(List<>)) {
var elementType = pt.GetGenericArguments()[0];
if (elementType == typeof(EmpRoles)) {
...
} else if (elenentType == typeof(EmpVisibility)) {
...
} else if ...
}
You can get generic parameter from list as following
var list = new List<EmpRoles>
var argType = list.GetType().GenericTypeArguments[0];
Here in argType you will get typeof(EmpRoles)
