1, VB.NET 读取 (通过streamReader)
' tmpCount = 0 'Dim tmpSR As New StreamReader(fileFullName,System.Text.Encoding.Default) 'Do While tmpSR.Peek >= 0 ' tmpCount = tmpCount + 1 'Loop 'tmpSR.Close()
2,通过VB.NET程序调用cmd命令
调用方法:fileRecordCounts = GetTxtRowCount(file)
fileShortName = System.IO.Path.GetFileName(file) ' 取短路径名
fileCreationDate = System.IO.File.GetCreationTime(file).ToString("yyyy MM dd HH:mm") ‘取文件创建时间
fileSize = New System.IO.FileInfo(file).Length / 1024 ’取文件大小, fileSize 为 KB
Private Function GetFileRowCount_Info(ByVal sFileFullName As String) As String If (Not File.Exists(sFileFullName)) Then Return "" Dim output As String = "" Try Dim myProcess As System.Diagnostics.Process = New System.Diagnostics.Process() myProcess.StartInfo.FileName = "cmd.exe" myProcess.StartInfo.UseShellExecute = False myProcess.StartInfo.RedirectStandardInput = True myProcess.StartInfo.RedirectStandardOutput = True myProcess.Start() Dim myStreamWriter As StreamWriter = myProcess.StandardInput myStreamWriter.WriteLine("find /V """" /C " + sFileFullName) myStreamWriter.Close() output = myProcess.StandardOutput.ReadToEnd() myProcess.WaitForExit() Catch ex As Exception Console.WriteLine(ex) Return "" End Try Return output End Function 'Dim result As Boolean = Int64.TryParse(value,number) ' If result Then ' Console.WriteLine("Converted '{0}' to {1}.",value,number) ' Else ' If value Is Nothing Then value = "" ' Console.WriteLine("Attempted conversion of '{0}' Failed.",value) ' End If Public Function GetTxtRowCount(ByVal sFileFullName As String) As Long If (Not File.Exists(sFileFullName)) Then Return -1 Dim sResult As String = GetFileRowCount_Info(sFileFullName) If (sResult = "") Then Return -1 Dim lResult As Long = 0 Dim lines() As String = sResult.Split(CChar(vbCrLf)) Dim sTmp As String = "" For Each s As String In lines sTmp = s.TrimEnd(CChar(vbCrLf)).ToUpper() If (sTmp = "") Then Continue For If (Not sTmp.Contains(".TXT")) Then Continue For If (Not sTmp.Contains("----------")) Then Continue For Long.TryParse(sTmp.Split(CChar(":"))(1).Trim(),lResult) ' 这里需要根据实际情况来 Exit For Next Return lResult End Function 'Public Function GetTxtRowCount(ByVal sFileFullName As String) As Integer ' If (Not File.Exists(sFileFullName)) Then Return -1 ' Dim sResult As String = GetFileRowCount_Info(sFileFullName) ' If (sResult = "") Then Return -1 ' Dim lResult As Integer = 0 ' Dim lines() As String = sResult.Split(System.Convert.tochar("\n")) ' Dim sTmp As String = "" ' For Each s As String In lines ' sTmp = s.TrimEnd(System.Convert.tochar("\r")).ToUpper() ' If (sTmp = "") Then Continue For ' If (Not sTmp.Contains(".TXT")) Then Continue For ' If (Not sTmp.StartsWith("----------")) Then Continue For ' Integer.TryParse(sTmp.Split(CChar(":"))(2).Trim(),lResult) ' Exit For ' Next ' Return lResult 'End Function
3, 通过C#程序调用cmd命令
调用方法: long iResult = Common.ConsoleCommand.GetTxtRowCount(sFileName);
public static string GetFileRowCount_Info(string sFileFullName) { if (!File.Exists(sFileFullName)) return ""; string output = ""; try { System.Diagnostics.Process myProcess = new System.Diagnostics.Process(); myProcess.StartInfo.FileName = "cmd.exe"; myProcess.StartInfo.UseShellExecute = false; myProcess.StartInfo.RedirectStandardInput = true; myProcess.StartInfo.RedirectStandardOutput = true; myProcess.Start(); StreamWriter myStreamWriter = myProcess.StandardInput; //myStreamWriter.WriteLine(sFileFullName.Substring(0,sFileFullName.IndexOf(":") + 1)); myStreamWriter.WriteLine("find /V \"\" /C " + @sFileFullName); myStreamWriter.Close(); output = myProcess.StandardOutput.ReadToEnd(); myProcess.WaitForExit(); } catch (Exception e) { Console.WriteLine(e); return ""; } return output; } public static long GetTxtRowCount(string sFileFullName) { if (!File.Exists(sFileFullName)) return -1; string sResult = GetFileRowCount_Info(sFileFullName); if (sResult == "") return -1; long lResult = 0; string[] lines = sResult.Split(System.Convert.tochar("\n")); string sTmp = ""; foreach (string s in lines) { sTmp = s.TrimEnd(System.Convert.tochar("\r")).ToUpper(); if (sTmp == "") continue; if (!sTmp.Contains(".TXT")) continue; // 不是.TXT的排除 if (!sTmp.StartsWith("----------")) continue; long.TryParse(sTmp.Split(':')[2].Trim(),out lResult); // 这里需要根据实际情况来 break; } return lResult; }
(结束)
