How can I capitalize each first letter of a word in a sentence? [duplicate]

Answer 1

Here's how I do it:

public static string ProperCase(string stringToFormat)
{
    CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;
    TextInfo textInfo = cultureInfo.TextInfo;

    // Check if we have a string to format
    if (String.IsNullOrEmpty(stringToFormat))
    {
        // Return an empty string
        return string.Empty;
    }

    // Format the string to Proper Case
    return textInfo.ToTitleCase(stringToFormat.ToLower());
}   

Answer 2

Maybe use the ToTitleCase method in the TextInfo class

How to convert strings to lower, upper, or title (proper) case by using Visual C#

CultureInfo cultureInfo   = Thread.CurrentThread.CurrentCulture;
TextInfo textInfo = cultureInfo.TextInfo;

Console.WriteLine(textInfo.ToTitleCase(title));

Answer 3

Try this:

        string inputString = "this is a test";

        string outputString = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(inputString);
