我很难理解下面这段 C# 代码示例的意思。测试类的集合(List)属性被设置为只读,但是在对象初始化器中似乎可以对其进行赋值。
** 编辑:已修复 List 'getter' 的问题
using System;
using System.Collections.Generic;
using NUnit.Framework;
namespace WF4.UnitTest
{
public class MyClass
{
private List<string> _strCol = new List<string> {"test1"};
public List<string> StringCollection
{
get
{
return _strCol;
}
}
}
[TestFixture]
public class UnitTests
{
[Test]
public void MyTest()
{
MyClass c = new MyClass
{
// huh? this property is read only!
StringCollection = { "test2", "test3" }
};
// none of these things compile (as I wouldn't expect them to)
//c.StringCollection = { "test1", "test2" };
//c.StringCollection = new Collection<string>();
// 'test1', 'test2', 'test3' is output
foreach (string s in c.StringCollection) Console.WriteLine(s);
}
}
}
