Lets break it down:

Cannot convert argument "collection"

The compiler can't convert between one type and another for the parameter called "collection"

with value: "System.Char[]"

Means you are passing a Char Array (System.Char[])

for "AddRange"

You are passing the Char Array to the AddRange method.

 to type "System.Collections.Generic.IEnumerable`1[System.Char[]]"

AddRange is expecting an IEnumerable (e.g. List or array) of Char Arrays

So, cant convert from Char Array to an Array/List of Char Arrays

So either:

  • You are calling the wrong method and should be calling Add not AddRange
  • or the type of your collection should be Char not Char[]
