删除文件名的子路径和创建文件结构

Question

我有以下List<String> fileNames获得通过我的方法， 我希望从删除子路径并创建离开了文件结构

string subPath = "C:\\temp\\test" 
List<string> filesIncoming = new List[]{@"C:\temp\test\a.txt", @"C:\temp\test\intest\a.txt"}; 
string outputDir = "C:\\temp3\\temp"; 

输出应该是：

C:\\temp3\temp\a.txt 
C:\\temp3\temp\intest\a.txt 

这是我想

foreach (var file in files) 
{ 
    var directory = Path.GetDirectoryName(file); 
    DirectoryInfo source = new DirectoryInfo(directory); 

    var fileName = Path.GetFileName(file); 
    var destDir = Path.Combine(destinatonFilePath, source.Name); //how do I remove sub-path from source.Name and combine the paths properly? 
    CreateDirectory(new DirectoryInfo(destDir)); 
    File.Copy(file, Path.Combine(destDir, fileName), true); 
}

我认为你应该使用旧的良好字符串。替换为从传入文件中删除公共基本路径，并将其替换为输出文件的公共基本路径

string subPath = "C:\\temp\\test" 
string outputDir = "C:\\temp3\\temp"; 

foreach (var file in files) 
{ 
    // Not sure how do you have named these two variables. 
    string newFilePath = file.Replace(subPath, outputDir); 
    Directory.CreateDirectory(Path.GetDirectoryName(newFilePath)); 
    File.Copy(file, newFilePath, true); 
}
