Declare a Dictionary inside a static class

Question

How to declare a static dictionary object inside a static class? I tried

public static class ErrorCode
{
    public const IDictionary E         


        

Answer 1

Create a static constructor to add values in the Dictionary

enum Commands
{
    StudentDetail
}
public static class Quires
{
    public static Dictionary quire
        = new Dictionary();
    static Quires()
    {
        quire.add(Commands.StudentDetail,@"SELECT * FROM student_b");
    }
}
