删除文本框中的第一个和最后一个单词 [英] removing first and last words in textbox

问题描述

嗨 我们正在搜索简历文本.
我们完成了布尔搜索(和运算).
它仅适用于我的搜索字符串(文本框字符串)包含"java和.net和C#或Sqlserver之类的....
但是问题是，
如果我的搜索字符串以"and"开头，以"and"结尾，那么我要先删除，最后是"and".不要删除中间的"and".这是我的搜索条件.



例如搜索字符串是这样的:

"and and and and and and asp.net and C#and Sqlserver and java and and and and ......
然后删除开始，结束和".
搜索仅像"asp.net和C#以及Sqlserver和Java"一样.
如何获得此?????????

Hi we are doing search on resume text.
we done the boolean search(and,or operations).
It Is working only for my search string (textbox string) contains "java and .net and C# or Sqlserver like....
But the problem is,
if my search string starts with "and" ,ends with "and" then i want to remove first,last "and" .Don''t remove the middle "and''s".this is my search criteria.



for example search string is like this:

"and and and and and asp.net and C# and Sqlserver and java and and and and...
Then it removes start,end "and".
searching is doing like " asp.net and C# and Sqlserver and java" only.
How can get this????????

推荐答案

这里是实现此功能的纯LINQ版本.

Here is pure LINQ version of implementing this functionality.

string searchInputs = "and and and and and asp.net and C# and Sqlserver and java and and and and";
string[] values = searchInputs.Split('' '');
var words = values.Skip(1).Take(values.Length - 2).ToList(); // Skip the first and the last words
StringBuilder sb= new  StringBuilder();
foreach (var word in words)
{
   sb.Append(word + " ");
}
tbSearch.Text = sb.ToString();

尝试:

string inp = "and and and and and asp.net and C# and Sqlserver and java and and and and";
string[] parts = inp.Split(new String[] {"and"}, StringSplitOptions.RemoveEmptyEntries);
StringBuilder sb = new StringBuilder();
string prefix = "";
foreach (string s in parts)
   {
   if (!string.IsNullOrEmpty(s.Trim()))
      {
      sb.Append(prefix);
      sb.Append(s);
      prefix = "and";
      }
   }
Console.WriteLine(sb.ToString().Trim());

它还会删除中间的重复和" ...

It also removes duplicate "and"s in the middle...
