Conversion a string to float

I have a problem with how to convert a string to a float. Here is my code on C#, please try to help me.

string Valeur = "16.2 dB";
Console.WriteLine(Valeur);
float seuil = 6;
string Valeur_optimisé = Valeur.Substring(0, Valeur.Length - 3);//Pour supprimer ( dB)
Console.WriteLine(Valeur_optimisé);
float var1 = (Convert.ToSingle(Valeur_optimisé));//J'ai une exception sur cette ligne
//Console.WriteLine(var1);
if (var1 < seuil)
{
Console.WriteLine("ERROR");
}
else

Console.WriteLine("OK");
}
Console.ReadKey();

You can also try:

float.Parse(Valeur_optimisé, CultureInfo.InvariantCulture.NumberFormat);

You can use something like this using TryParse

float var1;
Single.TryParse(Valeur_optimisé, out var1);
