问题描述
如何插入代码？信息，如果该文件是由其他程序打开                   &NBSP ;                        &NBSP ;                        &NBSP ;          
dim cse_name as string = sr_name +" output.cse"                                                                                                                   
如果file.exists = true，那么...                                                                                                                                                      
dim i1 as Integer = mesgbox（" ...，vbyesno） ENDIF                                                                                                                                                                           &NBSP ;                        &NBSP ;  
How can i insert a code for Info if the file is opened by an other program.
dim cse_name as string = sr_name + " output.cse"
if file.exists = true then ...
dim i1 as Integer =mesgbox("..., vbyesno) endif
sw1 = new IO.Streamwriter（cse_name） - >所以这里IOException问题，如果文件被打开。我怎样才能解决这个问题... 谢谢
sw1 = new IO.Streamwriter(cse_name) -> so here IOException problem if file is opened. How can i solve this problem... Thanks
推荐答案
你好lLikePP，
Hi lLikePP,
假设（如果文件未在其他任何地方打开）：您打开已打开的文件。确保所有已打开的流正常关闭。您也可以使用此语法。
Assumption (if file was not opened anywhere else) : You open already opened one.Make sure that all your opened streams closed properly. You can use this syntax too.
Using writer As StreamWriter = New StreamWriter(file)
writer.Write("....")
//and so on
End Using最好的问候，
