How to delete a row from a 2d array in c#? [duplicate]

Answer 1

string[] a = new string[] { "a", "b" }; //dummy string array
int deleteIndex = 1; //we want to "delete" element in position 1 of string
a = a.ToList().Where(i => !a.ElementAt(deleteIndex).Equals(i)).ToArray();

dirty but gives the expected result (foreach through the array to test it)

EDIT missed the "2d array" detail, here is the right code for the job

    string[][] a = new string[][] { 
        new string[] { "a", "b" } /*1st row*/, 
        new string[] { "c", "d" } /*2nd row*/, 
        new string[] { "e", "f" } /*3rd row*/
    };
    int rowToRemove = 1; //we want to get rid of row {"c","d"}
    //a = a.ToList().Where(i => !i.Equals(a.ElementAt(rowToRemove))).ToArray(); //a now has 2 rows, 1st and 3rd only.
    a = a.Where((el, i) => i != rowToRemove).ToArray(); // even better way to do it maybe

code updated
