Checking if a list of objects contains a property with a specific value

Question

Say I have the following code   class SampleClass       public int Id  get  set       public int Name  get  set     List lt SampleClass gt  myList   new List lt SampleClass gt       list is filled with objects     string nameToExtract    test     So my question is what List function can I use to extract from myList only the objects that have a Name property that matches my nameToExtract string   I apologize in advance if this question is really simple obvious

Further to the other answers suggesting LINQ  another alternative in this case would be to use the FindAll instance method   List lt SampleClass gt  results   myList FindAll x   gt  x Name    nameToExtract

You can use the Enumerable Where extension method   var matches   myList Where p   gt  p Name    nameToExtract     Returns an IEnumerable lt SampleClass gt   Assuming you want a filtered List  simply call  ToList   on the above     By the way  if I were writing the code above today  I d do the equality check differently  given the complexities of Unicode string handling   var matches   myList Where p   gt  String Equals p Name  nameToExtract  StringComparison CurrentCulture      See also
