多个文本到下拉列表 [英] multiple text to dropdownlist

问题描述

我有这样的字符串..
asdfg，ahahaha，ajajajaja

我想在下拉列表中插入文字

i have string like this ..
asdfg,ahahaha,ajajajaja

i want to insert text to dropdownlist
can some one halp me?

推荐答案

尝试:

string s = "asdfg,ahahaha,ajajajaja";
myDropDownList.Items.AddRange(s.Split(','));

如果您希望将csv值作为列表项插入，可以尝试以下代码示例.

您可以将ddlText替换为下拉列表的ID.

If you are looking to insert the csv values as list items you can try the below code sample.

You can replace ddlText with the ID of your dropdown list.

Dim strText As String = "asdfg,ahahaha,ajajajaja"

Dim strTextList As String() = strText.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries)

'remove the list items from dropdown
ddlText.Items.Clear()

'Add an empty ListItem
ddlText.Items.Add(New ListItem("", ""))

For i As Integer = 0 To strTextList.Length - 1
    ddlText.Items.Add(New ListItem(strTextList(i), strTextList(i)))
Next
