Question

C#中如何复制一个文件,粘贴到指定文件夹?

Answer 1

.NET类库提供了API

引用命名空间：using System.IO;

使用对象参考如下代码

c# code

 FileInfo f = new FileInfo("");

            f.CopyTo("");

Answer 2

使用FileInfo.CopyTo即可。
c# code如下：

FileInfo f = new FileInfo("file1");
f.CopyTo("file2");
注：file1和file2更换为对应的路径即可。

Answer 3

private void CopyDirectory(String source, String destination)
{
try
{

DirectoryInfo info = new DirectoryInfo(source);
FileSystemInfo[] sysInfos = info.GetFileSystemInfos();

foreach (FileSystemInfo fsi in info.GetFileSystemInfos())
{
string destName = Path.Combine(destination, fsi.Name);
//if file ,then copy it
if (fsi is System.IO.FileInfo)
{
string sourceName = Path.Combine(source, fsi.Name);
try
{
//just in case the destination is readonly
if (File.Exists(destName))
{
new FileInfo(destName).IsReadOnly = false;
}

File.Copy(fsi.FullName, destName, true);
}
}
}
}
}
