如何在c＃.net windows应用程序中拆分datagridview列值？ [英] Hhow to split datagridview column value in c# .net windows application?

问题描述

您好，



我想在六个变量中拆分一个datagridview列值，



我的Datagridview columna是这样的： -

Hello,

I want to split one datagridview column value in six variable,

My Datagridview columna like this:-

"\Library\Daino Royal - A.jpg,\Library\Abc.jpg,\Library\DEF.jpg,\Library\GHI.jpg,\Library\TIVOLI_GREY_A.jpg,\Library\URBANA_GREY - C.jpg"

我想在六个变量中仅填写.jpg文件，例如，

I want to fill only ".jpg" file in six variable like,

string a = "Abc.jpg";

那么，请帮助我如何拆分一个datagridview列值？



谢谢

推荐答案

这是一种做法...

Here''s one way of doing it ...

// copy the dgv value to a string e.g.
string dgvCell = dataGridView1.Rows[0].Cells[0].Value.ToString();

// Remove the /libary bits
dgvCell = dgvCell.Replace(@"\Library\", "");

//Use string.split to split on commas, store results in string array
string[] jpgList = dgvCell.Split(',');

// Do something with the results e.g. ...
foreach (string j in jpgList)
    if(j.Contains("jpg"))
        Debug.Print(j);

也试试这个正则表达式代码

also try this regex code

string s = @"\Library\Daino Royal - A.jpg,\Library\Abc.jpg,\Library\DEF.jpg,\Library\GHI.jpg,\Library\TIVOLI_GREY_A.jpg,\Library\URBANA_GREY - C.jpg";
 MatchCollection matches = Regex.Matches(s, @"(\w*.jpg)");
// or use MatchCollection matches = Regex.Matches(s, @"(\w*?\s*?-?\s*?\w*.jpg)");
//or use MatchCollection matches = Regex.Matches(s, @"((\w*?\s*?-?\s*?){0,}\w*.jpg)");
 string[] imgFileName = new string[matches.Count];
 int i=0;
 foreach (Match match in matches)
{
   imgFileName[i] = match.Value;
   MessageBox.Show(match.Value);
   i++;
}
