how to see if Listview column contains a specific name

Question

I have created a ListView with multiple columns

(This is a part of the Xaml)

<ListView.View> <GridView> <GridViewColumn Width="100" Header="Indexer" DisplayMemberBinding="{Binding Number}"/> <GridViewColumn Width="100" Header="Name" DisplayMemberBinding="{Binding NameId}"/> <GridViewColumn Width="100" Header="Age" DisplayMemberBinding="{Binding Age}"/> </GridView> </ListView.View>

cs part:

public class MyItem { public int Number { get; set; } public int Age { get; set; } public string NameId { get; set; } }

i know how to add a new item to a specific column:

AccountList.Items.Add(new MyItem { Age = Convert.ToInt32(AgeVAlue), NameId = NameValue.ToString(), Number = ListCount });

how do i check if NameId contains a spefic word because i cannot do this:

AccountList.Items.Contains(SpecificWord)
