Console.WriteLine String Replace String Uppercase First Letter

`ToTitleCase`

This uppercases each word in a String. Custom-developed algorithms may be superior. But the ToTitleCase function from System.Globalization is more convenient.

ToTitleCase is effective in many VB.NET programs. This example shows the ToTitleCase method on TextInfo from System.Globalization.

First, import the System.Globalization namespace. In Main, we use the TextInfo instance on CultureInfo.CurrentCulture and call ToTitleCase.

Result The output has each letter following a space or period uppercased. This is a simple example, so it works well.

Imports System.Globalization

Module Module1
    Sub Main()
        Dim value As String = "dot net perls vb.net"
        Dim title As String = CultureInfo.CurrentCulture.
            TextInfo.ToTitleCase(value)
        Console.WriteLine(title)
    End Sub
End Module
Dot Net Perls Vb.Net

A warning

Unfortunately, ToTitleCase does not contain extensive logic. It cannot handle special cases. For example, the acronym "VB.NET" is not uppercased correctly.

Info To solve this problem, you can call Replace on every special case you require.

There are many ways to do the same basic tasks in the .NET Framework. ToTitleCase is built into the .NET Framework for you, but it cannot cover every possible case you might require.
