How to declare and initialize constant strings in C#?
To set a constant in C#, use the const keyword. Once you have initialized the constant, on changing it will lead to an error.
Let’s declare and initialize a constant string −
const string one= "Amit";
Now you cannot modify the string one because it is set as constant.
Let us see an example wherein we have three constant strings. We cannot modify it after declaring −
Example
using System; class Demo { const string one= "Amit"; static void Main() { // displaying first constant string Console.WriteLine(one); const string two = "Tom"; const string three = "Steve"; // compile-time error // one = "David"; Console.WriteLine(two); Console.WriteLine(three); } }
Output
Amit Tom Steve
As shown above, if I will try to modify the value of constant string one, then it will show an error −
// compile-time error // one = "David";
