Generic Structs
Like generic classes, generic structs can have type parameters and constraints. The rules and
conditions for generic structs are the same as those for generic classes.
For example, the following code declares a generic struct called
PieceOfData
, which stores
and retrieves a piece of data, the type of which is determined when the type is constructed.
Main
creates objects of two constructed types—one using
int
and the other using
string
.
struct PieceOfData<T> // Generic struct
{
public PieceOfData(T value) { _Data = value; }
private T _Data;
public T Data
{
get { return _Data; }
set { _Data = value; }
}
}
class Program
{
static void Main()
Constructed type
{
↓
PieceOfData<int> IntData = new PieceOfData<int>(10);
PieceOfData<string> StringData = new
PieceOfData<string>(
"Hi there.");
↑
Constructed type
Console.WriteLine("IntData = {0}", IntData.Data);
Console.WriteLine("StringData = {0}", StringData.Data);
}
}
This code produces the following output:
IntData = 10
StringData = Hi there.
