public interface roman

    roman this[string name] { get; } 
} 

public class notempty : roman 
{ 
    public string Color{ get; set; } 

    public roman this[string name] 
    { 
     get { return new notempty() { Color= "Value1" }; } 
    } 
} 

Answer 1

public interface roman // there is an interface called "roman", accessible to all 
{ 
    // all implementations of "roman" must have an "indexer" that takes a string 
    // and returns another "roman" instance (it is not required to offer a "set") 
    // typical usage: 
    //  roman obj = ... 
    //  roman anotherObj = obj["abc"]; 
    roman this[string name] { get; } 
} 

public class notempty : roman // there is a class "notempty", accessible to all, 
{        // which implements the "roman" interface 

    // no constructors are declared, so there is a default public parameterless 
    // constructor which simply calls the parameterless base-constructor 

    // any instance of "notempty" has a string property called "Color" which can 
    // be both read (get) and written (set) by any callers; there 
    // is also a *field* for this, but the compiler is handling that for us 
    public string Color{ get; set; } 

    // there is an indexer that takes a string and returns a "roman"; since 
    // there is no *explicit* implementation, this will also be used to satisfy 
    // the "roman" indexer, aka "implicit interface implementation" 
    public roman this[string name] 
    { 
     // when the indexer is invoked, the string parameter is disregarded; a 
     // new "notempty" instance is created via the parameterless constructor, 
     // and the "Color" property is assigned the string "Value1"; this is then 
     // returned as "roman", which it is known to implement 
     get { return new notempty() { Color= "Value1" }; } 
    } 
} 

Answer 2

的Inferface 罗马定义了所有实现应该有一个索引 这[字符串名称]，返回罗马的一个实例。
