目录树阵列的路径

Question

我正在使用Directory.GetFiles来查找将要复制的文件。我需要找到文件的路径，以便我可以使用复制，但我不知道如何找到路径。 它遍历文件很好，但我不能复制或移动它们，因为我需要该文件的源路径。

这是我有：

string[] files = Directory.GetFiles(sourcePath, "*.*", SearchOption.AllDirectories); 

System.Console.WriteLine("Files Found"); 

// Display all the files. 
foreach (string file in files) 
{ 
    string extension = Path.GetExtension(file); 
    string thenameofdoom = Path.GetFileNameWithoutExtension(file); 
    string filename = Path.GetFileName(file); 

    bool b = false; 
    string newlocation = (@"\\TEST12CVG\Public\Posts\Temporaryjunk\"); 

    if (extension == ".pst" || 
    extension == ".tec" || 
    extension == ".pas" || 
    extension == ".snc" || 
    extension == ".cst") 
    { 
    b = true; 
    } 

    if (thenameofdoom == "Plasma" || 
    thenameofdoom == "Oxygas" || 
    thenameofdoom == "plasma" || 
    thenameofdoom == "oxygas" || 
    thenameofdoom == "Oxyfuel" || 
    thenameofdoom == "oxyfuel") 
    { 
    b = false; 
    } 

    if (b == true) 
    { 
    File.Copy(file, newlocation + thenameofdoom); 
    System.Console.WriteLine("Success: " + filename); 
    b = false; 
    } 
}

Path.GetFullPath作品，也可以考虑使用FileInfo，因为它附带了许多文件辅助方法。

我会使用类似的方法（可能会使用更多的错误处理（try ...渔获量），但它是一个良好的开端

编辑我注意到，你过滤掉了扩展，但要求他们，更新代码允许该

class BackupOptions 
{ 
    public IEnumerable<string> ExtensionsToAllow { get; set; } 
    public IEnumerable<string> ExtensionsToIgnore { get; set; } 
    public IEnumerable<string> NamesToIgnore { get; set; } 
    public bool CaseInsensitive { get; set; } 

    public BackupOptions() 
    { 
    ExtensionsToAllow = new string[] { }; 
    ExtensionsToIgnore = new string[] { }; 
    NamesToIgnore = new string[] { }; 
    } 
} 

static void Backup(string sourcePath, string destinationPath, BackupOptions options = null) 
{ 

    if (options == null) 
    optionns = new BackupOptions(); 

    string[] files = Directory.GetFiles(sourcePath, ".", SearchOption.AllDirectories); 
    StringComparison comp = options.CaseInsensitive ? StringComparison.CurrentCultureIgnoreCase : StringComparison.CurrentCulture; 

    foreach (var file in files) 
    { 
    FileInfo info = new FileInfo(file); 

    if (options.ExtensionsToAllow.Count() > 0 && 
     !options.ExtensionsToAllow.Any(allow => info.Extension.Equals(allow, comp))) 
     continue; 

    if (options.ExtensionsToIgnore.Any(ignore => info.Extension.Equals(ignore, comp))) 
     continue; 

    if (options.NamesToIgnore.Any(ignore => info.Name.Equals(ignore, comp))) 
     continue; 

    try 
    { 
     File.Copy(info.FullName, destinationPath + "\\" + info.Name); 
    } 
    catch (Exception ex) 
    { 
     // report/handle error 
    } 
    } 
} 

有了这样一个电话：

var options = new BackupOptions 
{ 
    ExtensionsToAllow = new string[] { ".pst", ".tec", ".pas", ".snc", ".cst" }, 
    NamesToIgnore = new string[] { "Plasma", "Oxygas", "Oxyfuel" }, 
    CaseInsensitive = true 
}; 

Backup("D:\\temp", "D:\\backup", options);
