这些标签有什么用？< employee> < / employee>，它给出了错误 [英] What is the use of these tags <employee> </employee>, it is giving error

问题描述

public List<Employee><employee> GetEmployees()
   {
       List<Employee><employee> employees = new List<Employee><employee>();
       Employee emp = new Employee();
       emp.FirstName = "johnson";
       emp.LastName = " fernandes";
       emp.Salary = 14000;
       employees.Add(emp);</employee>

当我使用这些标签时会发出错误

when I'm using these tags it's giving an error

<employee>

</employee>

我尝试过：



我正在尝试制作一个列表，因为我正在学习MVC

如果我能解决错误在使用Visual Studio 2012时，这部分代码来自7天内学习MVC。

What I have tried:

I'm trying to make a list as I'm learning MVC
how to fix the error if I'm using Visual Studio 2012,this part of code is from learn MVC in 7 days.

推荐答案

它不是标签 - 它是使用泛型类的C＃语法。

您可以阅读

It's not a tag - it's the C# syntax for using a generic class.
You can read

List<Employee> employees = new List<Employee>();

作为创建一个名为的变量员工其中包含一个Employee类实例列表，并为其分配一个新的Employee实例列表

当您创建一个Generic集合（其中List只是一个示例）时，您需要准确指定它可以包含哪些类（或基类）作为泛型是强类型的：除了正确的类的实例之外，你不能添加任何东西。因此，如果您声明一个双打列表：

As "Create a variable called employees which contains a List of Employee class instances, and assign a new empty List of Employee instance to it"
When you create a Generic collection (of which List is just one example) you need to specify exactly what class (or base class) it can contain as Generics are strongly typed: you can't add anything except instances of the right class to them. So if you declare a list of doubles:

List<double> myList = new List<double>();</double></double>

您可以添加双值，但不能添加整数：

You can add double values, but not integers:

int i = 666;
double d = 666.666;
myList.Add(d);  // Fine.
myList.Add(i);  // Compiler error.

与HTML不同，C＃不需要你关闭类型说明符 - 这只是HTML和XML的一个特性，而不是C＃源代码。

unlike HTML, C# does not need to you "close" the type specifier - that is a feature of HTML and XML only, not of C# source code.

这些标签有什么用？< employee> < / employee>

What is the use of these tags <employee> </employee>

这些标签是XML标签，您尝试在c＃程序中混合它们。问题是XML标签在C＃语言中是未知的，因此它们不会混合在一起。



你试图做的事情非常模糊。

These tags are XML tags and you try to mix them in a c# program. Problem is that XML tags are unknown from C# language and so they don't mix together.

What you try to do is pretty obscure.
