C-Sharp StrConv Example | ASP.NET C# StrConv Syntax | Source Code
Purpose: – Here is a StrConv Example that illustrates the C# Syntax in ASP.NET.
Step 1: Click on C# to Cut-n-paste code into StrConv.aspx.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; // 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 //**************************************************************************************** public partial class StringManipulation_StrConv : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Label1.Text = "Example #1: StrConv(string1,conversion,LocalId) "; string strString1 = "Hello"; TextBox1.Text = Microsoft.VisualBasic.Strings.StrConv(strString1, Microsoft.VisualBasic.VbStrConv.Lowercase, 0); //Returns hello } } |
Step 2: Click on XML to Cut-n-paste code into StrConv.aspx

- name of Web Site could be CSharp_ASPNET_Syntax.
- Add New folder named "StringManipulation"
- Right-click project name in solution explorer;
- add new folder;
- name of folder could be: StringManipulation
- Add Web Form Named StrConv.aspx to StringManipulation folder
- Right-click StringManipulation folder;
- add new item;
- Select Web Form
- Check place code behind in separate file
- Web Form name could be StrConv.aspx
- Click on C-Sharp in step 1 at the top of this page to copy code into web form StrConv.aspx
- Click on XML in step 2 above to copy code into code-behind StrConv.aspx.cs
