Controls how Unicode characters are interpreted by the HtmlDecode methods.
Assembly: System (in System.dll)
|Use automatic behavior. The decoding behavior is determined by current application's target Framework. For .NET Framework 4.5 and later, the Unicode encoding decoding is strict.|
|Use compatible behavior. Specifies that incoming data is not checked for validity before being decoded. For example, an input string of "&#xD84C;" would decode as U+D84C, which is an unpaired surrogate. Additionally, the decoder does not understand code points in the SMP unless they're represented as HTML-encoded surrogates, so the inputstring "𣎴" would result in the output string "𣎴".|
|Use loose behavior. Similar to in that there are no validity checks, but the decoder also understands code points. The input string "𣎴" would decode into the character U+233B4 correctly. This switch is meant to provide maximum interoperability when the decoder doesn't know which format the provider is using to generate the encoded string.|
|Use strict behavior. Specifies that the incoming encoded data is checked for validity before being decoded. For example, an input string of "𣎴" would decode as U+233B4, but an input string of "��" would fail to decode properly. Already-decoded data in the string is not checked for validity. For example, an input string of "\ud800" will result in an output string of "\ud800", as the already-decoded surrogate is skipped during decoding, even though it is unpaired.|
