关于读取文本文件的一些文摘
http://community.csdn.net/Expert/topic/3274/3274491.xml?temp=.4443323 给 AntingZ(夕惕若)的补充一下,凡用StreamReader,请习惯带上System.Text.Encoding.Default,要不我们
的中文就不能正确显示了。 Dim file As New System.IO.StreamReader("c:\test.txt", System.Text.Encoding.Default) Dim strLine As String strLine = file.ReadLine() '读第1行 MessageBox.Show(strLine) strLine = file.ReadLine() '读第2行 MessageBox.Show(strLine) file.Close()
回车chr(13) \r\n是换行回车 \n就回车

http://community.csdn.net/Expert/topic/2828/2828051.xml?temp=.508465 写 StreamWriter sw = File.AppendText(FilePath); sw.Close()
读 StreamReader sr = new StreamReader(".\\说明.txt",Encoding.Default); string input = ""; while((input = sr.ReadLine()) != null) { } sr.Close()
http://community.csdn.net/Expert/topic/2814/2814490.xml?temp=.7782404 \修改 FileStream fs = new FileStream(filename,FileMode.OpenOrCreate,FileAccess.Write,FileShare.Read); StreamWriter ww= new StreamWriter(fs,System.Text.Encoding.UTF8); ww.BaseStream.Seek(-6,SeekOrigin.End); ww.Write(text);.............
FileStream fs = new FileStream("c:\\test.txt",FileMode.OpenOrCreate,FileAccess.
ReadWrite,FileShare.Read); StreamWriter ww = new StreamWriter(fs,System.Text.Encoding.
Default); int pos = 6; byte[] lastByte = new byte[pos]; ww.BaseStream.Seek(-pos,SeekOrigin.End); fs.Read(lastByte,0,pos); string lastStr = System.Text.Encoding.Default.GetString(lastByte
); ww.BaseStream.Seek(-pos,SeekOrigin.End); string appendStr = "BBBBBB"; ww.Write(appendStr+lastStr); ww.Flush(); ww.Close(); fs.Close();
大文本文件计数 http://community.csdn.net/Expert/topic/2803/2803134.xml?temp=.6808435 int line_count=0; try { StreamReader sw=new StreamReader(File_path,System.Text.Encoding.GetEncoding("GB2312")); string line=""; while((line=sw.ReadLine())!=null) {line_count+=1;} sw.Close; } catch(Exception ex) {MessageBox.Show(ex.Message);}
如何将一个文本文件的内容清空,但不删除这文件 http://community.csdn.net/Expert/topic/2788/2788580.xml?temp=.4243738 Dim writer As New StreamWriter("c:\sample.txt", False) writer.Write(Nothing)
MessageBox.Show("一共有"+line_count.ToString()+"行");
C#写文本文件如何换行 http://community.csdn.net/Expert/topic/2725/2725488.xml?temp=.644848 webform ,c# 写文本文件。。 在后面加 \n , \n\r , \r\n 均不可以 出现状况为在win2K的记事本中换行的地方出现一个黑色的方块 但如果用 editplus等文本编辑软件打开则没有问题。。。。
应该怎么才能正确换行。。。。 vb.net中用 vbcrlf, c#中怎么用。。。
r\n should work
for example:
using System.IO;
StreamWriter sw = new StreamWriter("testfile.cs.txt",false, System.Text.Encoding.GetEncoding("GB
2312")); sw.Write("hello\r\nworld"); sw.Close();
如何获得文本文件的行数?在线等 http://community.csdn.net/Expert/topic/2662/2662493.xml?temp=.7574121 StreamReader sr = new StreamReader(filename); int line = 0; while (sr.ReadLine() != null) { line++; }
已经很完整了,另一个方法:这个方法可以扩展很多其他的应用: 对于学习熟悉文件结构很有好处: System.IO.StreamReader xx=new System.IO.StreamReader("F:\\a.txt"); int getB=xx.BaseStream.ReadByte(); int add=1; while(getB!=-1) { if(getB==13 && xx.BaseStream.ReadByte()==10){add++;xx.BaseStream.Position--;} getB=xx.BaseStream.ReadByte(); } this.label1.Text=add.ToString();
To bankliu(水岸) 其实单单只有字符'\n'或者'\r'也算换行,所以应该是这样: while(getB!=-1) { if(getB==13 || getB ==10){ add++; if (getB == 13 && xx.BaseStream.ReadByte()==10) xx.BaseStream.Position++; } getB=xx.BaseStream.ReadByte(); }
