C# get all elements of array

Question

Using array.ElementAt(0); we can get the element at index 0 of the array. Is there a method to get all the elements in an array?

string[] arr1 = {'abc', 'def', 'ghi'}
Library.Results["TEST_ACTUALVALUE"] = "The results are: " + arr1;

TEST_ACTUALVALUE is a column in my report.xls file. The above writes System.string[] in my excel file.

Answer 1

You already have all of the elements in the array...the array itself.

The simple answer is iterate over them:

foreach(var item in array)
{
    // work with item here
}

Or if you'd rather deal with indexes:

for(var i = 0; i < array.Length; i++)
{
    var item = array[i];
    // work with item here
}

Answer 2

It's hard to know what you mean by "get all the elements in an array" because you already have all the elements....in the array.

If you mean concatinating a string from a string array then something like:

var concatinatedString = String.Concat(myArrayOfStrings);
