Question

 String[] search1 = Directory.EnumerateFiles(voiceSource, callId + " "+ separator +"*."+ fileFormat +"")
                         .Where(file => Path.GetFileName(file).StartsWith( callId + " "+ separator +""))
                         .Select(path => Path.GetFileName(path))
                         .ToArray();

现在我想将以下数组复制到上面的search1中。换句话说，我想结合两个数组。

  String[] search2 = Directory.EnumerateFiles(voiceSource, callId + ""+ separator +"*."+ fileFormat +"")
                         .Where(file => Path.GetFileName(file).StartsWith(callId + ""+ separator +""))
                         .Select(path => Path.GetFileName(path))
                         .ToArray();

请注意，search1的长度可能为零。有什么帮助吗？

Answer 1

search3 = new type[search1.Length + search2.Length];
search1.CopyTo(search3, 0);
search2.CopyTo(search3, search1.Length);

其中type是数组中元素的类型
