IsNumeric function, which is a member of the
Microsoft.VisualBasic.Information class:

private void UseIsNumeric()

{

string s = "123";

bool bResult1, bResult2;

bResult1 = Information.IsNumeric(s);

// bResult1 now equals true

s = "Hello";

bResult2 = Information.IsNumeric(s);

// bResult2 now equals false;

}
