I have a textBox1 in my C# project. How can i use the IF statement if the value of textBox1 is greater than or equal to 75, the remarks is "Passed" else "Failed".

I used:

int a;
string remarks;

a = int.Parse(textBox1.Text);

If (a>=75) then
remarks="Passed"
Else
remarks="Failed"
End If

Kindly correct this?
