如何在c＃中将字符串行转换为修复大小数组？ [英] How to convert string line into fix size array in c#?

问题描述

大家好，



我在c＃中读取.txt文件。我有一个问题，如我的txt文件包含超过2000行，它将需要大量的时间来执行，因为目前我逐行读取并使用子字符串函数进行拆分数据。每行包含一个员工详细信息。在行中我将数据输入修复位置，例如，

Hi all,

I am reading .txt file in c#. I have one problem like my txt file contain more then 2000 lines and it will take lots of time to execute because currently i am read line by line and use sub-string function for split data. Each line contain one employee detail. In line i get data into fix position like,

Employee Name     = 0 to 50 Character,
Employee Address  = 51 to 200 Character,
Employee BDate    = 201 to 215 Character,
Employee Gender   = 216 to 220 Character
etc..

有没有读取线并使用此字段将其拆分为数组或其他内容的技术？我想提高性能。

Is there any technique to read line and split it to array or something else with this field? I want to improve performance.
