C# 如果包含相同的键，则替换另一个数组中的值

我有以下收藏

var collection = new []
{ 
   "First1",
   "Second2",
   "Third12"
}

然后我有一个查找表，其中包含需要替换的键：

var keys = new []
{ 
   Tuple.Create(1, "ABC"),
   Tuple.Create(2, "DEF")
}

最终结果应该是原始列表，其中包含从查找表中替换的值

var collection = new []
{ 
   "FirstABC",
   "SecondDEF",
   "ThirdABCDEF"
}

我尝试以下方式使用聚合函数：

    string[] collection = new[]{"First#", "Second@"};

    Console.WriteLine("Before {0}", String.Join(" - ", collection));

    var keys = new[]{Tuple.Create("#", "ABC"),Tuple.Create("@", "CDE")};
    foreach ( var item in collection)
    {
        if() // my item is in any occurrence of the keys array
    }

    Console.WriteLine("After {0}", String.Join(" - ", collection));

for（var i=0；i

for (var i = 0; i < collection.Length; i++)
{
    foreach (var k in keys)
    {
        collection[i] = collection[i].Replace(k.Item1, k.Item2);
    }
}
