var htmlContent = "";
for (var i = 0; i < 7; i++) {
htmlContent += " " + days[i] + "<br>";

using System;
namespace Tutorials
{
public partial class Web_Method : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[System.Web.Services.WebMethod]
public static string[] getArrayOfString()
{
string[] days = new string[7];
days[0] = "Sunday";
days[1] = "Monday";
days[2] = "Tuseday";
days[3] = "Wednesday";
days[4] = "Thursday";
days[5] = "Friday";
days[6] = "Saturday";
return days;
}
}
}
Output:
