        Dim dz_x As String = "C:\Users\zlm21\Desktop\"
        Dim n_x As String = TextBox1.Text
        If IO.Directory.Exists(dz_y) Then
            Button1.Enabled = False
            Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(dz_y, dz_x)
            Microsoft.VisualBasic.FileSystem.Rename("dz_x" + "DCIM", n_x)

Answer 1

目录的路径格式错误。
