If the requirement is to populate an array from the values of all rows of a DataTable corresponding to a particular Column without using a loop, then LINQ query can be used as follows:

C#

DataTable dataTable1 = new DataTable("DataTable1");
dataTable1.Columns.Add("Month", typeof(string),null);
dataTable1.Columns.Add("Name", typeof(string),null);
dataTable1.Columns.Add("Amout", typeof(int),null);

dataTable1.Rows.Add("March","John",0);
dataTable1.Rows.Add("April","Ishan",25);
dataTable1.Rows.Add("May","Raman",50);
dataTable1.Rows.Add("March","Sheron",0);
dataTable1.Rows.Add("March","Ramesh",75);

string[] names = dataTable1.AsEnumerable().Select (t => t.Field<string>("Name")).ToArray();

//Contents of names
//John 
//Ishan 
//Raman 
//Sheron 
//Ramesh</string>
