Here’s a sample code snippet demonstrating how you can easily decode a base64 encoded string in C#.
var base64EncodedString;//Fill this with your data. byte[] byteArray = Convert.FromBase64String(base64EncodedString); string output = Encoding.UTF8.GetString(byteArray);
When working in Win forms using C# and especially when you use the combo box , you would have noticed that by default the user can edit the values inside during the runtime.
Assuming that the combobox name is combobox1 , here the code to get this behavior.
comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;
There are times when you might want to get only the string AM or PM from the DateTime object that you have.
You can get this by using the format specifiers in the ToString method as shown in the code snippet.
using System;
namespace AbundantcodeApp
{
class Program
{
static void Main(string[] args)
{
var Data =
DateTime.Now.ToString("tt", System.Globalization.CultureInfo.InvariantCulture);
Console.WriteLine(Data);
Console.ReadLine();
}
}
}Write a program in Microsoft Visual C# that takes a number as input and prints its multiplication table.
using System;
namespace AbundantcodeApp
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Abundantcode.com coding sample");
int number;
Console.WriteLine("Enter the Number : ");
number = int.Parse(Console.ReadLine());
for (int i = 1; i <= 10; i++)
Console.WriteLine(number + " x " + i + " = " + number * i);
Console.Read();
}
}
