title: how can I convert a c# variable of type double to sql float
body: <p>I am using a variable type of double in c#
  and I want to insert it in an sql row in sql server.</p>
  <p>I read the variable from keyboard (implementing a console application)
  the problem that I understand that C# has different format than sql server...</p>
  <p>e.g. the number 12,34 in c# is equivalent to 12.34 in sql server...</p>
  <p>how can I make the conversion so to insert it to the row I want?</p>
