在列表框中的字符之间插入空格

问题描述

我正在尝试将项目插入到我的 asp.net C# 应用程序的列表框中

I am trying to insert items into a listbox in my asp.net C# application

我连接了一些值并在它们之间放置了空格，但它没有显示在列表框中.

I concatenate some values and put whitespace in between them but it doesn't show up in the listbox.

        ListItem lt = new ListItem();
        lt.Text = ItemName + "    " + barcode + "    " + price; // problem
        lt.Value = barcode;
        lstMailItems.Items.Add(lt);

我什至尝试过

lt.Text = ItemName + "		" + barcode + "		" + price; // problem
lt.Text = ItemName + "& nbsp;" + barcode + "& nbsp;" + price; // &nbsp shows up as text

但这似乎不起作用.如何在这些字符串之间放置空格，以便它也显示在列表框中

but that even doesn't seem to work. How can I put whitespace between these strings so that it shows up in the listbox as well

推荐答案

string spaces = Server.HtmlDecode("    "); 

lt.Text = ItemName + spaces + barcode + spaces + price; // works
