最近在项目中有用到写Log 的功能.用VB.Net写的.如下:
1 Public Sub WriteLog(ByVal Msg As String)
2
3 Dim varAppPath As String
4 varAppPath = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "log"
5 System.IO.Directory.CreateDirectory(varAppPath)
6
7 Dim head As String
8 head = System.DateTime.Now.Hour.ToString() + ":" + System.DateTime.Now.Minute.ToString()
9 head = head + ":" + System.DateTime.Now.Second.ToString() + ":" + System.DateTime.Now.Millisecond.ToString()
10 Msg = head + System.Environment.NewLine + Msg + System.Environment.NewLine
11
12 Dim strDate As String
13 strDate = System.DateTime.Now.ToString("yyyyMMdd")
14 Dim strFile As String
15 strFile = varAppPath + "\" + strDate + ".log"
16 Dim SW As System.IO.StreamWriter
17 SW = New System.IO.StreamWriter(strFile, True)
18
19 SW.WriteLine(Msg)
20 SW.Flush()
21 SW.Close()
22
23 End Sub
