xsd regex pattern converted to vb.net regex pattern

This is quite simple
Convert the following xsd patterns to System.Text.RegularExpressions.Regex.Replace(string,regex expression,"") which will be used in vb.net

' MetalDescription <xs:pattern value="^[a-z|A-Z|0-9|\s\-_\#]*$" />
'idn <xs:pattern value="^[a-z|A-Z|0-9]+$">
First Name <xs:pattern value="^[a-z|A-Z|\s\-]+$"></xs:pattern> '
'Last Name <xs:pattern value="^[a-z|A-Z|\s\-]+$"></xs:pattern>
'seller address street <xs:pattern value="^[a-z|A-Z|0-9|\s\/\#\,\.]+$">
'seller address city <xs:pattern value="^[a-z|A-Z|\s]+$">
'seller address zip <xs:pattern value="^\d{5}([\-]\d{4})?$">
'vehicle plate <xs:pattern value="^[a-z|A-Z|0-9]+$"></xs:pattern>

There apparently some formatting differences between xsd regex patterns and vb.net regex patterns and I need them converted to regex patterns for vb.net of which I plan on using like this System.Text.RegularExpressions.Regex.Replace(string,regex expression,"") in vb.net

I need this project done in minutes and not hours/days...
