将文件从一个目录复制到另一个目录 [英] Copy file from one directory to another
问题描述
我对C#来说还很陌生,我正在尝试让我的程序将文件从一个位置复制到另一个位置。我的方法如下;
private void CopyInstallFiles(object sender,EventArgs e)
{
字符串sourceFile = F:\\inetpub\ftproot\test.txt;
string copyPathone = directoryImput.Text;
System.IO.File.Copy(sourceFile,copyPathone);
}
您可以找到一个固定的来源位置,但是目的地是从用户输入(文本框)。但是,我遇到的问题是,当我尝试复制到某个位置时,例如C:\testfolder。我收到了非法字符异常。
File.Copy 需要目的地的完整文件名。
destFileName
类型:System.String
目标文件的名称。这不能是目录。
如果您输入的只是文件夹名称,则需要添加源文件的文件名。
private void CopyInstallFiles(object sender,EventArgs e)
{
// a的正确语法路径名需要逐字@ char
字符串sourceFile = @ F:\inetpub\ftproot\test.txt;
字符串文件= Path.GetFileName(sourceFile);
string copyPathone = directoryImput.Text;
System.IO.File.Copy(sourceFile,Path.Combine(copyPathone,file),true);
}
请注意,最后一个参数= true会覆盖目标文件夹中的文件。 / p>
作为旁注,我建议您删除文本框作为文件夹名称的输入,而应使用文件夹浏览器对话框
I am pretty new to C# and I am trying to get my program to copy a file from one location to another. The method I have is as below;
private void CopyInstallFiles(object sender, EventArgs e)
{
string sourceFile = "F:\\inetpub\ftproot\test.txt";
string copyPathone = directoryImput.Text;
System.IO.File.Copy(sourceFile, copyPathone);
}
As you can is there is a fixed source location however the destination is taken from user input (text box). The problem I have however, is that when I try to copy to a location for example C:\testfolder. I get an illegal character exception.
File.Copy requires the full filename for the destination.
destFileName
Type: System.String
The name of the destination file. This cannot be a directory.
If your input is just the folder name then you need to add the filename of the source file.
private void CopyInstallFiles(object sender, EventArgs e)
{
// The correct syntax for a path name requires the verbatim @ char
string sourceFile = @"F:\inetpub\ftproot\test.txt";
string file = Path.GetFileName(sourceFile);
string copyPathone = directoryImput.Text;
System.IO.File.Copy(sourceFile, Path.Combine(copyPathone, file), true);
}
Note the final parameter = true to overwrite a file in the destination folder.
As a side note, I suggest you to remove the textbox as input for a folder name but instead use the FolderBrowserDialog
