data type error

sathish

Hi,

I have assign the variable as "public string Test"

Now I have to take the value on that as Boolean - true or false

So I have made the below conversion
Convert.ToBoolean(Test.Equals("1") ? true : false)

but when the Test value comes as null .. I'm gettting object reference error

Kindly help on this.

Thanks

Sathish

Hi all i think its not big deal to convert string value to bool
just check string value is null or not and then convert.

Somehow, I fail to understand why we need Convert.ToBoolean at all?

Is following not good enough?

public String Test;

Boolean Test1 = String.IsNullOrEmpty(Test) ? false : (Test == "1" ? true : false);

Hi,

Try this code :
using System;

public class Program
{
    public static string Test;
    public static void Main()
    {
        bool Test1 = Convert.ToBoolean(Test == "1" ? true : false);
        Console.WriteLine(Test1);
    }
}

Hi ,

try this

if(!string.IsNullOrEmpty(Test)) // or if(Test!=null)
{
Convert.ToBoolean(Test.Equals("1") ? true : false)
}
