Passing Single-Dimensional Arrays As Arguments
For example, the following statement sends an array to a print method.
class MainClass
{
public static void Main()
{
int[] theArray = { 1, 3, 5, 7, 9 };
PrintArray(theArray);
}
public static void PrintArray(int[] arr)
{
foreach (int i in arr)
{
System.Console.WriteLine(i);
}
}
}
The output:
1
3
5
7
9
You can initialize and pass a new array in one step, as is shown in the following example.
class MainClass
{
public static void Main()
{
PrintArray(new int[] { 1, 3, 5, 7, 9 });
}
static void PrintArray(int[] arr)
{
foreach(int i in arr){
System.Console.WriteLine(i);
}
}
}
The output:
1
3
5
7
9
In the following example, an array of strings is initialized and passed as an argument.
class MainClass
{
static void PrintArray(string[] arr)
{
for (int i = 0; i < arr.Length; i++)
{
System.Console.Write(arr[i] + "{0}", i < arr.Length - 1 ? " " : "");
}
}
static void Main()
{
// Declare and initialize an array.
string[] weekDays = { "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat" };
// Pass the array as an argument to PrintArray.
PrintArray(weekDays);
}
}
The output:
Sun Mon Tue Wed Thu Fri Sat
