How to String Title Case

Title case is a convention in which the first character of a word is converted to uppercase, while the remaining characters are converted to lowercase. This formatting style is commonly used for titles, headings, and proper nouns.

CultureInfo class

In the .NET Framework, the CultureInfo class plays a crucial role in rendering culture-specific information. It provides access to a wide range of data associated with a particular culture, including language, sublanguage, country/region, calendar systems, and cultural conventions. By utilizing the CultureInfo class, developers can retrieve and utilize culture-specific information based on the needs of their application.


In the context of culture codes, a neutral culture is represented by a two-letter lowercase language code. For instance, "fr" signifies the neutral culture for French, while "de" denotes the neutral culture for German. Neutral cultures are used to specify the broad language category without specifying a specific country or region.

Dim cultureInfo As New System.Globalization.CultureInfo("en-US")

Within the .NET Framework, the String class indirectly uses the CultureInfo class to obtain information about the default culture. This allows developers to ensure that string operations, formatting, and conversions align with the cultural conventions of the current environment.The follwoing VB.NET source code shows how to convert a string to Title Case.

Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim _str As String Dim cultureInfo As New System.Globalization.CultureInfo("en-US") _str = cultureInfo.TextInfo.ToTitleCase("make first letter capital") MsgBox(_str) End Sub End Class


Using the CultureInfo class and its associated culture-specific information, developers can create applications that are sensitive to cultural nuances and provide a localized experience for users. Understanding how the String class indirectly utilizes the CultureInfo class helps ensure that applications handle string data appropriately based on the default culture or any specific culture specified.
