C#泛型编程用于FORM调用,简化代码

使用

FormMngr<FormQry>.showMdiChild<FormQry>(this);
实现

public class FormMngr<T> where T : Form
{
public static int I = 0;
private static System.Collections.SortedList fList = new System.Collections.SortedList();
public static void showMdiChild<T>(Form p_midparnt) where T : new()
{
string me = typeof(T).ToString();
if (fList.Contains(me))
{
Form f = fList[me] as Form;
(f as Form).Activate();
return;
} else
{
T fqry = (T)new T();
(fqry as Form).MdiParent = p_midparnt;//.M;
fList.Add(me, fqry);
(fqry as Form).Show();
}
}

}
