文本文件信息到SQL
我需要编写一个程序，从文本文件中获取信息并将其上传到SQL中的表中。
所以，我写了一个小程序，从文本文件中获取信息并将其放入TextBoxes，这似乎有效：
using (System.IO.StreamReader file = new
System.IO.StreamReader(@"C:\Users\Chriss\Desktop\Test Eq\ATE4 Dbase 2017-05-12 - Copy.log"))
{
string allFile = file.ReadToEnd();
int offset = 0;
int length = 3;
if (allFile.Substring(offset, length) == "NEW")
{
textBox1.Text = allFile.Substring(4, 10);
textBox2.Text = allFile.Substring(15, 8);
textBox3.Text = allFile.Substring(24, 22);
textBox4.Text = allFile.Substring(47, 4);
textBox5.Text = allFile.Substring(53, 7);
}
问题是某些“字段”的字符长度发生了变化，所以我不能去特定位置获取信息。可能有帮助的另一件事是不同的“字段”用“Tab”空格分隔。这就是文本文件的样子：
从文本文件中获取该信息的最佳方法是什么？

3 个答案:
答案 0 :(得分：0)
如果字段或列中没有tab的可能性，则可以使用string.Split（）
答案 1 :(得分：0)
您可以在每个单词的开头和结尾使用字符分隔符。这样，即使字段长度不同，您也必须只搜索字段分隔符（char（28）Ascii值）。对于不同的行，您可以设置段分隔符（char（30））。如果需要进一步分离，则可以使用组分离器（char（29））。
例如： 聊天（30）+ char（28）+ STP + char（28）+ 3char（28）+ P + char（28）+ CHECKL + char（28）+ PACKAGING-VISUAL INSPECTION ..... next line 聊天（30）+炭（28）+ + STP炭（28）+ 3char（28）+ ..... 等等
