Sort A List
MyListName->Sort();
Sort A List Of Custom Classes
You need to add a CompareTo method to the class which will be used when Sort is called. It needs to be virtual for C++/CLI and you also need to add :IComparable to the class definition.
Example For An Int Value
(Uses a '.' for the CompareTo call)
public ref class MyMainClassName : IComparable<MyMainClassName ^>
{
public:
property List<MyClassName^> ^MyClassNames;
...
}
public ref class MyListClassName
{
public:
property String ^MyString;
property int MyInt;
MyListClassName::MyListClassName(void)
{
//Strings and arrays will be nullptr until created
MyString = "";
}
//Add CompareTo to allow sorting of list
virtual int MyListClassName::CompareTo(MyListClassName ^other)
{
return other->MyInt.CompareTo(this->MyInt); //<<Reverse to reverse sorting order
}
};
MyMainClassName ^MyMainClassName1 = gcnew...
...
MyMainClassName->Sort();
Example For A String Value
(Uses '->' for the CompareTo call)
public ref class MyMainClassName : IComparable<MyMainClassName ^>
{
public:
property List<MyClassName^> ^MyClassNames;
...
}
public ref class MyListClassName
{
public:
property String ^MyString;
property int MyInt;
MyListClassName::MyListClassName(void)
{
//Strings and arrays will be nullptr until created
MyString = "";
}
//Add CompareTo to allow sorting of list
virtual int MyListClassName::CompareTo(MyListClassName ^other)
{
return other->MyString->CompareTo(this->MyString); //<<Reverse to reverse sorting order
}
};
MyMainClassName ^MyMainClassName1 = gcnew...
...
MyMainClassName->Sort();
