如何在c#中制作参数化属性

how to make parameterized properties in c#

推荐答案

以下是在MSDN中找到的示例:

here is an example found in MSDN:

public WebSite this[int index]
{
   get
      {    
          if (index > sites.Count)    
            return (WebSite)null;    

          return (WebSite) sites.GetByIndex(index);
      }
   set
      {    
         if ( index < 10 )    
           sites[index] = value;
      }
}

如果我没记错的话，唯一可以参数化的属性就是索引器.

The only parametrized properties you can make are indexers if I am not mistaken.

您可以在C#中创建的参数化属性的唯一类型是索引器属性:

The only type of parameterized property you can create in C# is an indexer property:

public class MyConnectionStrings
{
    private string GetConnectionString(string connectionName) { ... }

    public string this[string connectionName]
    {
        get { return GetConnectionString(connectionName); }
    }
}

否则，只需创建一个方法即可-似乎更接近您要查找的方法，如:

Otherwise, just create a method instead - that seems to be closer to what you are looking for, a shown in :
