Question

我已经实现了这样的代码，我从中得到了这个想法。

public string BrowseFolder()
{
    string filePath = string.Empty;
    OpenFileDialog openFileDialog1 = new OpenFileDialog();
    openFileDialog1.Multiselect = true;
    openFileDialog1.Title = "Browse EXCEL File";
    openFileDialog1.Filter = "Excel Files (*.xlsx)|*.xlsx";

    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        filePath = openFileDialog1.FileName;
        return Path.GetDirectoryName(filePath);
    }

    return null;
}


public void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);
    DirectoryInfo[] dirs = dir.GetDirectories();

    // If the source directory does not exist, throw an exception.
    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    // If the destination directory does not exist, create it.
    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }

    // Get the file contents of the directory to copy.
    FileInfo[] files = dir.GetFiles();

    foreach (FileInfo file in files)
    {
        // Create the path to the new copy of the file.
        string temppath = Path.Combine(destDirName, file.Name.ToString());

        // Copy the file.
        file.CopyTo(temppath, false);
    }

    // If copySubDirs is true, copy the subdirectories.
    if (copySubDirs)
    {
        foreach (DirectoryInfo subdir in dirs)
        {
            // Create the subdirectory.
            string temppath = Path.Combine(destDirName, subdir.Name);

            // Copy the subdirectories.
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }
}

好的，我们假设这两个方法都在一个类中。我很容易理解这些代码是如何工作的。它正在复制我浏览的文件夹中的所有文件。这不是我需要的。我想要实现的是只复制我的文件夹中的选定文件（多个）。

我试图操纵我的代码，但我仍然没有得到正确的解决方案。提前谢谢。

Answer 1

foreach (string file in openFileDialog1.FileNames)
{
    FileInfo fInfo = new FileInfo(file);
    fInfo.MoveTo(newFilePath);
}

您需要从OpenFileDialog中选择所有文件：

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
    string[] filesSelected = openFileDialog1.FileNames;    
}

上面的代码返回用户从OpenFileDialog中选择的所有文件。

将多个选定文件移动到特定文件夹
