How to String to Boolean?

Answer 1

You can use Convert.ToBoolean("true") or Convert.ToBoolean("false")

if you have values such as yes or no then you can use an if statement

string s="Yes";
bool result=false;
if(s=="Yes")
{
result= true;
}
else
{
result=false;
}

Answer 2

What about null?

string s = "";

bool? result = null;

if(s == "Yes")

 result = true;

elseif(s == "No")

 result = false;
