string.split方法未在定界符之间给出空字符串 [英] string.split method doesnt give the empty string between delimiters

问题描述

你好，

我正在使用string.split方法拆分字符串

例如我有以下字符串

61a | a62a | a63a | aa | a65a | a

您看到63之后应该有一个空字符串要返回，但不是，我该怎么做，请帮我

hello,

I am splitting the string using string.split method

for example i have the following string

61a|a62a|a63a|aa|a65a|a

you see after 63 there should be an empty string to be returned but its not, how can i do that please help me

推荐答案

使用StringSplitOptions.None代替StringSplitOptions. RemoveEmptyEntries

use StringSplitOptions.None instead of StringSplitOptions.RemoveEmptyEntries

试试这个:

Hi,
Try this:

private void ReadFileData(string path)
{
    string line;
    string[] delimiters = new string[] { "a|a" };
    try {
        using (StreamReader file = new StreamReader(path))
        {
            while ((line = file.ReadLine()) != null)
            {
                string[] parts = line.Split(delimiters, StringSplitOptions.None);
                WriteDateToSQL(parts);
            }
            file.Close();
        }
    }
    catch (Exception e) {
        MessageBox.Show(e.ToString());
    }
}

祝一切顺利.

如果需要在a | a上断开字符串，请执行以下操作:

If you need to break the strings on a|a do the following :

string str = "61a|a62a|a63a|aa|a65a|a";
var strarray = str.Split(new string[] { "a|a" }, StringSplitOptions.None);
