推荐答案

步骤1->在文件打开对话框(设置属性Multiselect = true)中创建一个循环(foreach)，该循环将迭代所选文件的数量.

2->在此循环中编写文件读取代码，使用循环的迭代变量中的文件名.

3->在读取代码下方编写您的新文件创建和编写代码(仅在循环内)

4->循环结束.

标记为答案(如果有帮助的话，它会激发您的兴趣):)

step 1 -> create a loop (foreach), which will iterate for number of files you have selected, in file open dialogue box (set property Multiselect = true).

2 -> write your file reading code inside this loop, use the filename from the iteration variable of your loop.

3-> write your new file creation and writing code below the reading code (inside the loop only)

4 -> end of loop.
