我几天前开始学习编程，我正在一个同时复制和粘贴几个文件的程序上工作/练习，但是当要让它在多个不同的扩展上工作时，我就遇到了麻烦
这是密码
null
namespace practice
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
public string[] getFlies
{
get;
set;
}
public string getdirectory
{
get;
set;
}
public string[] getextension
{
get;
set;
}
private void button1_Click(object sender, EventArgs e)
{
try
{
OpenFileDialog getfiles = new OpenFileDialog();
getfiles.Filter = "All Files (.)|.";
getfiles.FilterIndex = 1;
getfiles.Multiselect = true;null
我该怎么办？
我建议您将变量的名称改为更好的名称。但为了与您的代码保持一致，我使用了您选择的名称。br>好的，您可以这样做:
// instead of string[].
public FileInfo[] getFlies { get; set; } // I suggest to change the name, maybe to Files?
// in your button1_click method, after the DialogResult is OK
// getFiles in the dialog and getFlies is the array.
public void button1_Click(object sender, EventArgs e)
{
var getfiles = new OpenFileDialog(); // again, change the name...maybe for dialog?
getfiles.Filter = "All Files (*.*)|*.*"; // I fixed it. You missed the '*' .
// more dialog initialization
if(Dialog.Result.OK == getfiles.ShowDialog())
{
getFlies = getfiles.FileNames.Select( f => new FileInfo(f)).ToArray();
}
}
// Now, in button3_click
void button3_Click(object sender, EventArgs e)
{
foreach(var file in getFlies)
{
File.Copy(file.FullName, Path.Combine(getdirectory, file.Name));
}
}
