# 方法重载
|
|||
|
|
|||
|
默认参数是在C#4.0版本中引入的,但直到那时,C#编码器一直在使用不同的技术,这种技术基本上是相同的,称为方法重载。它允许程序员定义几个具有相同名称的方法,只要它们采用不同的参数集即可。当您使用.NET框架的类时,您很快就会意识到在整个地方都使用了方法重载。
|
|||
|
|
|||
|
## 例
|
|||
|
|
|||
|
1. 创建一个名为Person.cs的类文件并输入以下代码。 \`\`\` 公共阶层人 { public string FirstName {get;私人集; } public string LastName {get;组; }
|
|||
|
|
|||
|
public Person(string firstName,string lastName) { this.FirstName = firstName; this.LastName = lastName; }
|
|||
|
|
|||
|
public string SayHello(字符串名称) { 返回“你好,”+名称; }
|
|||
|
|
|||
|
公共字符串SayHello(人) { 返回“Hello there,”+ person.FirstName +“”+ person.LastName; } }
|
|||
|
|
|||
|
```
|
|||
|
2. In your default Program.cs file you can call now this class Person using the method overloading.
|
|||
|
```
|
|||
|
|
|||
|
课程 { static void Main(string \[\] args) { 人物=新人(“简”,“美国能源部”); Console.WriteLine(person.SayHello(“Peter Smith”));
|
|||
|
```
|
|||
|
Person friend = new Person("Chuck", "Norris");
|
|||
|
Console.WriteLine(person.SayHello(friend));
|
|||
|
|
|||
|
Console.ReadKey();
|
|||
|
|
|||
|
|
|||
|
}
|
|||
|
}
|
|||
|
```
|
|||
|
|
|||
|
