我正在开发一个程序来寻找特定的文件类型(一个文件夹中只存在一种)。我选择文件夹,扫描它以查找文件类型,以防他找到文件流并将查询结果写入文本框。
这是我到目前为止所得到的:
For Each file1 In IO.Directory.GetFiles(folderA, file_A)
Using fich_time As New StreamReader(file1)
line = fich_time.ReadLine
Try
myStream_time = file1.OpenFile()
If (myStream_time IsNot Nothing) Then
line = fich_time.ReadLine
While Not fich_time.EndOfStream
If line.Contains(" CPU Time for A Analysis") Then
If line.Contains("sec") = True Then
txt_A.Text = line
txt_A.Text = Replace$(txt_A.Text, Space(1), Space(0))
txt_A.Text = Regex.Replace(txt_A.Text, "[^0-9.]", "")
Else
txt_A.Text = line
txt_A.Text = Replace$(txt_A.Text, Space(1), Space(0))
txt_A.Text = Regex.Replace(txt_A.Text, "[^0-9.]", "")
txt_A.Text = txt_A.Text * 3600
End If
End If
End While
End If
Finally
End Try
End Using
Next
主要的错误是OpenFile方法是字符串的成员,到目前为止我知道但是我应该使用什么函数来使这个工作?
最好的问候其他人
试试这个,别忘了关闭你的文件
For Each file1 In IO.Directory.GetFiles(folderA, file_A)
Using fich_time As New StreamReader(file1)
Try
While Not fich_time.EndOfStream
line = fich_time.ReadLine
If line.Contains(" CPU Time for A Analysis") Then
If line.Contains("sec") = True Then
txt_A.Text = line
txt_A.Text = Replace$(txt_A.Text, Space(1), Space(0))
txt_A.Text = Regex.Replace(txt_A.Text, "[^0-9.]", "")
Else
txt_A.Text = line
txt_A.Text = Replace$(txt_A.Text, Space(1), Space(0))
txt_A.Text = Regex.Replace(txt_A.Text, "[^0-9.]", "")
txt_A.Text = txt_A.Text * 3600
End If
End If
End While
Catch ex As Exception
MsgBox(ex.Message)
Finally
fich_time.Close()
End Try
End Using
Next
