C# syntax to initialize custom class/objects through constructor params in array?

Question

I have a class with minimum 4 variables and I have made a constructor for the class so that I can initialize it with

MyClass testobj = new MyClass(1234,56789,"test text", "something else", "foo");

Works fine.

Then I have an array of these, that I need to parse in a loop, so I would like to get some static data into this array.

My approach was:

MyClass[] testobjlist = new MyClass 
{
     new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
     new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
     new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
};

but somehow this gives me a weird error about me needing an extra } ???

I don't know if I should mention this, but I use it for webpages using Razor-engine 2. But I think this is an ordinary C# question?

My workaround is currently to initialize the array with a size, then adding the elements one by one through index, but I would rather prefer the above solution as I might have to move the items up and down in order when testing and I have a lot more than 3 in the real data.

Wondering what I am missing in the above code?

I have no clue why this was downvoted? – Ringmaster

Problem semi-solved by using a simple and more n-tier approach. Strange behaviour for Razor Engine, but I dont mind, now the code works as originally expected. That's what counts right now. I marked the answer + made a comment on how. – Ringmaster

Please don't modify your question in a way such that existing answers no longer make sense. (this was years ago, but came back to it just now and had no clue why none of the answers made any sense) – Unlock

Answer 1

Try adding square brackets after new MyClass and a semi-colon at the end

    MyClass[] testobjlist = new MyClass[] 
        {
         new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
         new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
         new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
        };

aaah, well I only forgot that in my example here. They are in the real version and it still gives me an error. So strange. – Ringmaster

Strange, I tried to place the exact same code into a separate BAL class, and now everything works as expected. But if I place the code inside the @{} code-strip in the .cshtml file I get the error about missing }. Probarbly a Razor engine bug. Thanks for your help anyways. – Ringmaster

Answer 2

Shorthand for the win:

var myClassList = new[]
{
    new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
    new MyClass(1002,2345,"Text xx", "bla bla", "dong")
};

Answer 3

this will also work without a need to create a constructure

new MyClass [] { new MyClass { Field1 = "aa", Field2 = 1 } }

Answer 4

You want:

MyClass[] testobjlist = new MyClass[] { ... }

You were missing the brackets toward the end.

Answer 5

MyClass[] testobjlist = 
    {
     new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
     new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
     new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
    };

Answer 6

MyClass[] testobjlist = new MyClass[noOfObjects];
for(int i = 0; i < testobjlist.Length; i++) { testobjlist[i] = new MyClass(); }

Answer 7

You can use below code for the array:

additionalusers[] __adiitonaluser =
{
    new additionalusers()
};
__adiitonaluser[0].Email = Userpersonal.Email;

Answer 8

MyClass[] testobjlist = new MyClass[] 
{
     new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
     new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
     new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
};

Or

MyClass[] testobjlist =
{
     new MyClass(1001,1234,"Text 1", "abcdefghijklm", "ding"),
     new MyClass(1002,2345,"Text xx", "bla bla", "dong"),
     new MyClass(1003,8653,"Text yy", "blah blah even more", "bamm!")
};
