How to: Validate Text for Display in a Web Browser in Visual Basic
This example demonstrates how to use the HtmlEncode method to ensure that a browser correctly displays text. Characters in a string such as <
, >
, and &
are rendered incorrectly unless they are escaped as <
, >
, and &
.
Example
The following code example encodes a string to be displayed in a browser. It encodes the string named TestString
, which contains the text This is a <Test String>
, and copies it into the string named EncodedString
as This is a <Test String>
.
Dim TestString As String = "This is a <Test String>"
Dim EncodedString As String = Server.HtmlEncode(TestString)
This example requires a reference to System.Web.dll.
