Utilize String.Trim():

"    aaa    ".Trim()
// "aaa"

To remove only spaces in beginning of the string, use String.Trimstart()

"    aaa    ".TrimStart()
// "aaa    "

To remove only spaces in end of the string, use String.Trimend()

"    aaa    ".TrimEnd()
// "    aaa"

Well, only at the beginning or end is it like the Fábio Perez said, but every sentence can be like this:

string frase = "Isso é uma string"; // Declaramos a string
string sem = ""; // Declaramos o futuro resultado
foreach (char c in frase.ToCharArray()) // Para cada 'letra' na frase
{
    if (c != ' ') // Se a letra não for um espaço
        sem += c; // É adicionada a string final
}
Console.WriteLine(sem); // Escrevemos a string final no console

That gives the result:

This is a string
