使用System.IO模块 使用函数 openBinaryFile :: FilePath -> IOMode -> IO Handle 打开文件 IOMode为 ReadWriteMode, 不然会截断文件 eg: h <- openFile "b.txt" ReadWriteModehPutChar h 'b'hPutChar h 'b'hPutChar h 'b'hPutChar h 'b'hPutChar h 'b'hClose h 如果处理二进制文件 要引入

Python读取txt文件,有两种方式: (1)逐行读取 data=open("data.txt") line=data.readline() while line: print line line=data.readline() (2)一次全部读入内存 data=open("data.txt") for line in data.readlines(): print line
//1.打开资源管理器 OpenFileDialog open = new OpenFileDialog(); if (open.ShowDialog() == DialogResult.OK) { textBox1.Text =open.FileName; } //传入txt文件路径参数 读取txt文件所有内容 返回DATATABLE public DataTable GetTxt(string pths) { StreamReader sr = new S
