How to Remove multiple items in List using RemoveAll on condition?
c#, linq, linq-to-sql
Solution
You only need one lambda expression - the `||` goes within that:
MyList.RemoveAll(t => t.Name == "ABS" || t.Name == "XYZ" || t.Name == "APO");
In other words, "Given a `t`, I want to remove the element if `t.Name` is ABS, or if `t.Name` is XYZ, or if `t.Name` is APO."
There's only one "given a `t`" in there, which is what the `t =>` part means, effectively.
Problem
I tried like following. ``` MyList.RemoveAll(t => t.Name == "ABS"); MyList.RemoveAll(t => t.Name == "XYZ"); MyList.RemoveAll(t => t.Name == "APO"); ``` Instead how can I do something like: ``` MyList.RemoveAll(t => t.Name == "ABS" || t => t.Name == "XYZ" ||t => t.Name == "APO"); ```
