I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

You must use some of the C   conversion systems        string to boolean  True to true   string str    True   bool mybool   System Convert ToBoolean str        boolean to string  true to True   bool mybool   true  string str   System Convert ToString mybool      or  string str   mybool ToString      bool Parse expects one parameter which in this case is str  even    Convert ToBoolean expects one parameter   bool TryParse expects two parameters  one entry  str  and one out  result     If TryParse is true  then the conversion was correct  otherwise an error occurred  string str    True   bool MyBool   bool Parse str      Or  string str    True   if bool TryParse str  out bool result          Correct conversion   else          Incorrect  an error has occurred
