泛型怎么写
1.返回值是泛型怎么写
是 C++ 语言语法吗?
#include "stdafx.h"
#include
using namespace std;
//返回泛型的全局函数
template T func(T t)
{
return t;
}
template class A
{
public:
//返回泛型的类成员函数函数
T func(T t)
{
return t;
}
};
int _tmain(int argc, _TCHAR* argv[])
{
cout a;
cout
2.java class 泛型怎么写
E - Element (在集合中使用,因为集合中存放的是元素) T - Type(Java 类) K - Key(键) V - Value(值) N - Number(数值类型) ? - 表示不确定的java类型举例说明: Set
泛型的作用: 1、用泛型: Java代码 收藏代码List
3.c#泛型,懂c#的进来帮忙下,泛型方法写呢
public class AccountInfo
{
public AccountInfo ( string userName, string password, string email)
{
this.UserName = userName;
this.Password = password;
this.Email = email;
}
public string UserName
{
get;
set;
}
public string Password
{
get;
set;
}
public string Email
{
get;
set;
}
}
System.Collections.Generic.IList<AccountInfo> list = new System.Collections.Generic.List<AccountInfo> ( );
list.Add ( new AccountInfo ( "User Name 1", "Password 1", "Email 1" ) );
list.Add ( new AccountInfo ( "User Name 2", "Password 2", "Email 2" ) );
list.Add ( new AccountInfo ( "User Name 3", "Password 3", "Email 3" ) );
this.grdEmployees.DataSource = dstXML.Tables [ 0 ].DefaultView;// grdEmployees是GridView
this.grdEmployees.DataBind ( );
//补充泛型方法
private System.Collections.Generic.IList<AccountInfo> GetAccounts()
{
System.Collections.Generic.IList<AccountInfo> list = new System.Collections.Generic.List<AccountInfo> ( );
list.Add ( new AccountInfo ( "User Name 1", "Password 1", "Email 1" ) );
list.Add ( new AccountInfo ( "User Name 2", "Password 2", "Email 2" ) );
list.Add ( new AccountInfo ( "User Name 3", "Password 3", "Email 3" ) );
return list;
}
4.返回值是泛型怎么写
是 C++ 语言语法吗?#include "stdafx.h"#includeusing namespace std;//返回泛型的全局函数template T func(T t){ return t;}template class A{public: //返回泛型的类成员函数函数 T func(T t) { return t; }};int _tmain(int argc, _TCHAR* argv[]){ cout A a; cout system("pause"); return 0;}。
