如何在列表视图中合并并找到子字符串 [英] How to concat and find substring in listview

问题描述

专家，


我正在开发c锋利的应用程序.

现在，我在Listview中显示数据库结果.

像下面一样，

Hi Expert,


I am developing c sharp application.

Now i am showing database results in Listview.

Like following,

<%# Eval("category1")%>
<%# Eval("category2")%>
<%# Eval("category3")%> 

现在，我必须用半列分隔符和从0到45的子字符串来合并以上3个结果.

我如何才能实现这样的目标.

Now I have to concat above 3 results with semicolumn separator and substring starting from 0 to 45.

How i can achieve like this.


Thanksssssssss in advance.

推荐答案

嗨
string.Format("{0}，{1}，{2}"，Eval("category1")，Eval("category2")，Eval("category3")).Substring(0,45)

Hi
string.Format("{0},{1},{2}",Eval("category1"),Eval("category2"),Eval("category3")).Substring(0,45)

串联运算符&用于解决此问题

Concatenation operator & is used to solve this problem

<![CDATA[<%= Eval("category1") & ";" & Eval("category2") & ";" & Eval("category3")%>]]>
