vb.net - 逗号分隔的数组项列表

Question

VB.NET 中是否有一个内置函数，它可以接受一个字符串数组并输出一串逗号分隔的项目？

示例:function( { "Sam","Jane","Bobby"} ) --> "Sam, Jane, Bobby"

Answer 1

String.Join(",", YourArray) 

此外，如果您想从复选框列表(或单选按钮列表)中获取所有选定项目，您可以使用扩展方法(复选框列表如下所示):

调用语法: Dim sResults As String = MyCheckBoxList.ToStringList()

    <Extension()> _
    Public Function ToStringList(ByVal cbl As System.Web.UI.WebControls.CheckBoxList) As String
        Dim separator As String = ","
        Dim values As New ArrayList
        For Each objItem As UI.WebControls.ListItem In cbl.Items
            If objItem.Selected Then
                values.Add(objItem.Value.ToString)
            End If
        Next
        Return String.Join(separator, values.ToArray(GetType(String)))
    End Function
