Type.GetType({型名})で取得できるタイプの中身を調べるType.FindMembersで見つけたサンプルをちょっこっと加工したもの。
// ToSearch フィルター

if (mems.Length > 0)
{
for (int j = 0; j < mems.Length; j++)
{
list.Add($"{t} {mt}'s supported: {mems[j].ToString()}.");
}
}
else
{
// list.Add($"{t} does not implement the {mt}'s {filter}.");
}
}// GetMemberTypesAll
public static void GetMemberTypesAll(Type t, List<string>list)
{
if (!listA.Exists(x => x == t.FullName))
{
listA.Add(t.FullName);
GetMemberTypes(t, MemberTypes.Constructor,list);

//以下はオマケ。
GetTypeInterfaces(t, list);
GetMembers(t, list);
}
}// FindInterfaces
public static List<string> listA = new();
public static void GetTypeInterfaces(Type t, List<string> list)
{
string filter = "*";
TypeFilter myFilter = new TypeFilter(ToSearch);
Type[] myInterfaces = t.FindInterfaces(myFilter, "*");
if (myInterfaces.Length > 0)
{
list.Add($"{t} implements the interface {filter}.");
for (int j = 0; j < myInterfaces.Length; j++)
{
list.Add($"> Interfaces supported: {myInterfaces[j]}.");
//
string iTypename = myInterfaces[j].ToString();
Type? t2 = Type.GetType(iTypename);
if (t2 != null)
{

}
}
}
}
else
{
// list.Add($"{t} does not implement the interface {filter}.");
}
}
// GetMembers
public static void GetMembers(Type t, List<string> list)
{
// Get the MemberInfo array.
MemberInfo[] members = t.GetMembers();
// Get and display the name and the MemberType for each member.
list.Add($"Members of {t.Name} ({members.Length})");
foreach (var member in members)
{
MemberTypes memberType = member.MemberType;
list.Add($"> {member.Name}: {memberType}");
}
}をこんな感じで呼び出す。
