如何使用特殊字符，如'＆LT;“或'＆安培;'在XML文件生成在vb.net [英] how to use special characters like '<' or '&' in XML file generation in vb.net

问题描述

我将数组传递给一个函数数组转换为XML。但我不能够使用特殊字符，如＆LT;或＆放大器;。当我通过这些提示错误无效的XML文件中。

I am passing an array to a function which converts the array to an XML. But I am not able to use special characters like "<" or "&". When I pass these it gives error invalid XML file.

Protected Sub drawgraph(ByRef dt As DataTable, ByVal name As String)
    Try

        Dim n(dt.Columns.Count - 3) As String
        Dim r(dt.Columns.Count - 3) As String

        For i As Integer = 1 To dt.Columns.Count - 2
            ***n(i - 1) = dt.Columns(i).ColumnName.ToString.Replace("<", "&lt;")***

            r(i - 1) = (dt.Rows(0).Item(i))
        Next
        ChartBuilder1.BuildLabel(n)
        ChartBuilder1.BuildValues(r, "Age Profile")

        ChartBuilder1.GenerateGraph()
        ChartBuilder1.Visible = True
    Catch ex As Exception
        lbl_msg.Text = ex.Message
    End Try
End Sub

我将＆LT;与＆放大器; LT;，但它不工作

推荐答案

使用HttpServerUtility.HtmlEn code逃离特殊字符。

Use HttpServerUtility.HtmlEncode to "escape" the special characters.

＆LT;成为＆放大器; LT;
