Hi to all, i have created a class named subfileInfo:

 public class SubFileINfo    {       public string Name;       public UInt32 StartOffset;       public UInt32 Length;    }

and i have an arrary of subfileInfo

SubFileInfo[] SubFileArray;

now i need to find in my SubFileArray the subfilesinfo that has in their names the string contained in textbox1.text

I am trying to do this wit Array.find but i am very confused i don´t achive to do it, How can i search for the subfilesinfo which contains into their name the substring textbox1.text

I think this should work:

SubFileINfo info = Array.Find(SubFileArray, sfi => sfi.Name.Contains(textbox1.text));

The => syntex is called a lambda expression, you can google that for more info.

The MSDN page shows an example without lambda expressions, which might be easier to understand.

Thank´s for the help, i have another question, normally that will find more than one elementswhich have the substring textbox1.tex in their name, could i make the operation you wrote me saving the results into a FileInfo array?
