Get string pattern c#

Hi,

 

I have an expression as follows,

 

Code = 'H1' and Code = 'B1' and Name = 'Hary' and City = 'siegel' 

 

I need a part of string which contains same field. For eg. in above expression 'Code is repeating and hence I need  only Code = 'H1' and Code = 'B1' in seperate variable.

 

Any help would be appreciated.
