convert string to boolean

Question

Hi, wanna ask, how to change this code to accept boolean base on a string. 

 

I have a CSV file that has pressure column and I want to make it as a boolean if the value is 'pressure is ok' it will convert to boolean and save it to the database with 'pressure is ok' 

 

if (i == 0)

{
    cmd.Parameters.AddWithValue("pressure", columns[i]);

}

 

can somebody help me ?

Thank you
