從Dictionary的值中獲取名稱，以逗號分隔的值字符串

Question

我有一個字典Dictionary<int, Foo> fooDic ，因為它的價值是一類和Foo有一個屬性_barName我需要所有的名字fooDic為CSV串...例如..

var fooDic = new Dictionary<int, Foo>()
{
    { 0, new Foo { _barId = 10, _barName = "some value" } },
    { 1, new Foo { _barId = 15, _barName = "some Foo value" } }, 
    { 2, new Foo { _barId = 25, _barName = "some Foobar value" } }
};

我需要輸出為

string result = "some value, some Foo value, some Foobar value";

請分享您的想法/解決方案，如何實現？
