SQL

to pass an array from server side to access it from client side we can use RegisterArrayDeclaration method.

Here is a simple example

In your code behind you can use the method like,

protected void Page_Load(object sender, EventArgs e)
{
RegisterArrayDeclaration("MyArray", "'Welcome'");
RegisterArrayDeclaration("MyArray", "'Hai'");
RegisterArrayDeclaration("MyArray", "'Hello'");
RegisterArrayDeclaration("MyArray", "'Best'");
RegisterArrayDeclaration("MyArray", "'Super'");
}

You can access this array from client side Javascript code,

C#

for (var i = 0; i < MyArray.length; i++) {
       alert(MyArray[i]);
}
