How to initialize a string to an empty string in C#?
To initialize a string to an empty list −
string myStr = null;
Now, use the built-in method IsNullOrEmpty() to check whether the list is empty or not −
if (string.IsNullOrEmpty(myStr)) {
Console.WriteLine("String is empty or null!");
}Let us see the complete code −
Example
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
string myStr = null;
if (string.IsNullOrEmpty(myStr)) {
Console.WriteLine("String is empty or null!");
}
Console.ReadKey();
}
}
}Output
String is empty or null!
Another way to initialize a string to an empty string, try the following code. Here, we have used string.Empty −
Example
using System;
namespace Demo {
public class Program {
public static void Main(string[] args) {
string myStr = string.Empty;
if (string.IsNullOrEmpty(myStr)) {
Console.WriteLine("String is empty or null!");
} else {
Console.WriteLine("String isn't empty or null!");
}
}
}
}Output
String is empty or null!
