How do I cast object to Boolean value from database.

this is throwing invalid case excetion.

emp.IsActive = (bool)rdr["Is_Active"];
emp.IsActive = Convert.ToBoolean(rdr["Is_Active"]);

What I have tried:

emp.IsActive = (bool)rdr["Is_Active"];
emp.IsActive = Convert.ToBoolean(rdr["Is_Active"]);

Solution 2

check Boolean.TryParse Method (String, Boolean) (System)[^]

bool isActive = false;
          if (bool.TryParse(rdr["Is_Active"] + "", out isActive)) {
              emp.IsActive = isActive
          }
          else
          {
             // show the error message to the user
          }
