How to make a first letter capital in C#

Question

How can the first letter in a text be set to capital?

Example:

it is a text.  = It is a text.

Answer 1

polygenelubricants' answer is fine for most cases, but you potentially need to think about cultural issues. Do you want this capitalized in a culture-invariant way, in the current culture, or a specific culture? It can make a big difference in Turkey, for example. So you may want to consider:

CultureInfo culture = ...;
text = char.ToUpper(text[0], culture) + text.Substring(1);

or if you prefer methods on String:

CultureInfo culture = ...;
text = text.Substring(0, 1).ToUpper(culture) + text.Substring(1);

where culture might be CultureInfo.InvariantCulture, or the current culture etc.
