我想浏览pdf文件并将其存储在另一个文件夹中。我已经实现了pdf文件浏览部分。我可以得到所有的pdf文件路径。现在我想把它们保存在另一个文件夹中。有办法做到这一点吗？

    //Keep pdf file locations
    List<string> pdfFiles = new List<string>();
    // Browse pdf and get their paths
    private void btnPdfBrowser_Click(object sender, EventArgs e)
    {
        OpenFileDialog openFileDialog = new OpenFileDialog();
        openFileDialog.CheckFileExists = true;
        openFileDialog.AddExtension = true;
        openFileDialog.Multiselect = true;
        openFileDialog.Filter = "PDF files (*.pdf)|*.pdf";
        if (openFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            foreach (string fileName in openFileDialog.FileNames)
            {
                pdfFiles.Add(fileName);
            }
        }
    }
    private void btnUploadFile_Click(object sender, EventArgs e)
    {
        string installedPath = Application.StartupPath + "pdf";
        //Check whether folder path is exist
        if (!System.IO.Directory.Exists(installedPath))
        {
            // If not create new folder
            System.IO.Directory.CreateDirectory(installedPath);
        }
        //Save pdf files in installedPath ??
    }

浏览并保存pdf文件C#winform

怎么样

File.Copy(sourcePath, destinationPath);

以下是的完整代码片段

//Keep pdf file locations
List<string> pdfFiles = new List<string>();
// Browse pdf and get their paths
private void btnPdfBrowser_Click(object sender, EventArgs e)
{
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.CheckFileExists = true;
    openFileDialog.AddExtension = true;
    openFileDialog.Multiselect = true;
    openFileDialog.Filter = "PDF files (*.pdf)|*.pdf";
    if (openFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        pdfFiles = new List<string>();  
        foreach (string fileName in openFileDialog.FileNames)
            pdfFiles.Add(fileName);
    }
}
private void btnUploadFile_Click(object sender, EventArgs e)
{
    string installedPath = Application.StartupPath + "pdf";
    //Check whether folder path is exist
    if (!System.IO.Directory.Exists(installedPath))
    {
        // If not create new folder
        System.IO.Directory.CreateDirectory(installedPath);
    }
    //Save pdf files in installedPath
    foreach (string sourceFileName in pdfFiles) 
    {
        string destinationFileName = System.IO.Path.Combine(installedPath, IO.Path.GetFileName(sourceFileName));
        System.IO.File.Copy(sourceFileName, destinationFileName);
    }
}

当您循环浏览所有pdf时，或者当您想将它们移动到File.Move 时，可以使用File.Copy方法
