// This example is from http://idealprogrammer.com
// It shows how you can use StrConv syntax in C-Sharp ASP.NET
 
//****************************************************************************************
// Example #1: 	StrConv(string1,conversion,LocalId) - returns string converted as specified
// string1 - Required. String expression to be converted.
// conversion - Required. VbStrConv member. The enumeration value specifying the type of 
//   conversion to perform.
// LocalId - Optional. The LocaleID value, if different from the system LocaleID value. 
// (The system LocaleID value is the default.)
// 
// Enumeration(member)         Description()
// VbStrConv.None()            Performs no conversion
// VbStrConv.LinguisticCasing() Uses linguistic rules for casing, rather than File System 
// (default). Valid with VbStrConv.UpperCase and VbStrConv.LowerCase only.
// VbStrConv.Uppercase()       Converts the string to uppercase characters.
// VbStrConv.Lowercase()       Converts the string to lowercase characters.
// VbStrConv.ProperCase()      Converts the first letter of every word in string to uppercase.
// VbStrConv.Wide*              Converts narrow (half-width) characters in the string to wide
//  (full-width) characters.
// VbStrConv.Narrow*            Converts wide (full-width) characters in the string to narrow 
// (half-width) characters.
// VbStrConv.Katakana**          Converts Hiragana characters in the string to Katakana characters.
// VbStrConv.Hiragana**          Converts Katakana characters in the string to Hiragana characters.
// VbStrConv.SimplifiedChinese* Converts Traditional Chinese characters to Simplified Chinese.
// VbStrConv.TraditionalChinese* Converts Simplified Chinese characters to Traditional Chinese.
// * - Chinese locales only
// ** - Japanese locales only
