The C# equivalent is a using alias directive
using StringList = System.Collections.Generic.List<string>;
The syntax for C++ is: . E.g.
Using the C++ Standard Library, we could use following to create a templated list of type string and iterate through it.
list<string> items;
for (list<string>::const_iterator it = items.begin(); it != items.end(); it++)
{
string str = *it;
}
We can simplify the above by creating a type alias using typedef.
typedef list<string> StringList;
StringList items;
for (StringList::const_iterator it = items.begin(); it != items.end(); it++)
{
string str = *it;
}
As an alternative to typedef, we could create a new class dervied from the original type with public accessibility.
class CStringList : public std::list<std::string>
{
}
CStringList items;
for (CStringList::const_iterator it = items.begin(); it != items.end(); it++)
{
string str = *it;
}

C# doesn't support the typedef keyword, but just like C++, we have options.
1. Create a type synonym with a using alias directive. This is similar to typedef.
using StringList = System.Collections.Generic.List<string>;
...
StringList items = new StringList();
foreach (var item in items)
{
Console.WriteLine(item);
}
2. Create a new class derived from the original type
class CStringList : List<string>
{
}
...
CStringList items = new CStringList();
foreach (var item in items)
{
Console.WriteLine(item);
}
