C# What's the best way to make a table with 2 columns and more than 20 verses in which one column is string and second int.

Question

In the first column i wanna store string type values and in the second one i wanna store int type values. For example:
John 3
Mark 4
Max 8
Additionally i want the values to be changeable. I would like to set the program to increase Mark's value by 1 if some event happens. For example:
John 3
Mark 4
Max 8
After Event n. 1
John 4
Mark 4
Max 8
After Event n. 2
John 4
Mark 5
Max 8
I would also like to be able to show it on console.
Sorry for my english and poor description. I am a beginner.
