C# 文件复制和移动操作（单个文件）

string path = @"d:\EM1.txt";
            string path2 = @"d:\云轩\EM2.txt";
            FileInfo fi1 = new FileInfo(path);
            FileInfo fi2 = new FileInfo(path2);
 
            try
            {
                // Create the source file.
                // using (FileStream fs = fi1.Create()) { }
                //Ensure that the target file does not exist.
                if (File.Exists(path2))
                {
                    fi2.Delete();
                }
                //Copy the file.f
                fi1.CopyTo(path2);
                Console.WriteLine("{0} was copied to {1}.", path, path2);
            }
            catch (IOException ioex)
            {
                Console.WriteLine(ioex.Message);
            }

C# 复制文件（文件夹）

string pLocalFilePath ="";//要复制的文件路径
string pSaveFilePath ="";//指定存储的路径
if (File.Exists(pLocalFilePath))//必须判断要复制的文件是否存在
{
File.Copy(pLocalFilePath, pSaveFilePath, true);//三个参数分别是源文件路径，存储路径，若存储路径有相同文件是否替换
}
