            File.Copy(dirPath + @"\" + name, tarPath + @"\" + name);
        }//end of CopyFile

Simple function use examples ：

ControlFileClass.CopyFile(rootPath + @"\" + "wybnmsl", rootPath + @"\" + "moguwai", "1.txt");
ControlFileClass.MoveFile(rootPath + @"\" + "wybnmsl", rootPath + @"\" + "moguwai", "2.txt");

If it is a console application directly, then copy , Cutting is moving , It's easy to understand , Because the direct current path and target path are known . But in winform In development , This is different , Because clicking copy or cut on a control only knows the current path , Do not know the target path . Then at this time, we need to copy and move Process segmentation , Here is an example ：

stay 345 Under the folder , I click item xxxxxxx.txt, At this time, I pass menupath When the click event is recorded ,listview Medium item The path of

private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
        {
            ContextMenuStrip menu = (ContextMenuStrip)sender;
            ListView livi = (ListView)menu.SourceControl;
            //ToolStripItem toolStripItem = (ToolStripItem)livi.SelectedIndices;
            ListView.SelectedIndexCollection c = livi.SelectedIndices;

            menupath = livi.FocusedItem.Tag.ToString();// Record which item Next 


            // Determine whether the right button position has item
            if (c.Count > 0)
            {
                // Yes item Right click menu will be displayed normally 
            }
            // No, item There was no response 
            else
                e.Cancel = true;
        }

At this point, this click event is recorded for all functions in the right-click menu menupath, Then right click the menu （ToolStripMenuItem） Any operation in the needs to use the corresponding item All positions are ok

Such as cutting and copying , Then simply record menupath that will do

private void  Copy ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            originpath = menupath;
            if (ControlFileClass.IsFolder(menupath))
            {
                MessageBox.Show(" Copying folders is not supported ");
            }
            else
            {
                MessageBox.Show(" Copy file succeeded ");
            }
            COM = 1;

        }
private void  shear ToolStripMenuItem_Click(object sender, EventArgs e)
        {
            originpath = menupath;
            if (ControlFileClass.IsFolder(menupath))
            {
                MessageBox.Show(" Cutting folders is not supported ");
            }
            else
            {
                MessageBox.Show(" Copy and cut succeeded ");
            }
            COM = 2;
        }

Then when pasting , At this time menupath It's the destination address , and originpath It is the original address recorded above , At this point, you can complete the move or copy from the original address to the target address

private void  Paste ToolStripMenuItem1_Click(object sender, EventArgs e)
        {
            if (!ControlFileClass.IsFolder(menupath))
            {
                MessageBox.Show(" Paste failed , The paste target should be folder ");
            }
            else
            {
                string filename = ControlFileClass.GetFileName(originpath);
                originpath = ControlFileClass.GetFolderPath(originpath);
                if (COM == 1)
                {
                    ControlFileClass.CopyFile(originpath, menupath, filename);
                    COM = 0;
                }
                else if (COM == 2)
                {
                    ControlFileClass.MoveFile(originpath, menupath, filename);
                    COM = 0;
                }
                else
                {
                    MessageBox.Show(" There are no files in the clipboard ");
                }
                
            }
             Knowledge base refresh (fenquname);
        }
