C# 接口

[modifiers] interface IName [: Interface [, Interfaces]]
{
// methods
// properties
// indexers
// events
}

看看C# 几口的定义  比起java 的却是要麻烦些  不过概念还是一样的

C#  构造函数重载

public class WebSite
{
string siteName;
string url;
string description;
// Constructors
public WebSite()
: this(“No Site”, “no.url”, “No Description”) {}
public WebSite(string newSite)
: this(newSite, “no.url”, “No Description”) {}
public WebSite(string newSite, string newURL)
: this(newSite, newURL, “No Description”) {}
public WebSite(string newSite,
string newURL,
string newDesc)
{
siteName    = newSite;
url         = newURL;
description = newDesc;
}
}
