How do you translate this from VB.NET TO C#.NET

    Private ReadOnly c_bKey() As Byte = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}
    Private ReadOnly c_bIv() As Byte = {8, 7, 6, 5, 4, 3, 2, 1}

Thanks...

byte[] c_bKey = new byte[] {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24};
byte[] c_bIv = new byte[] {8, 7, 6, 5, 4, 3, 2, 1};

By the way.. There are online/desktop utilities available for the translation.

Ah! The Byte and byte are two different things... Gotcha!

I'm still getting a compile error, so I'll just post the whole thing here to see if anyone can help me out... The compiler error kept complaining about "this.c_bKey[]" & "this.c_bIv[]"... I post a seperate code for the foo class.

//This code...

private byte[] c_bKey = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 };
private byte[] c_bIv = new byte[] { 8, 7, 6, 5, 4, 3, 2, 1 };
private EncryptionType c_oEncryption = new EncryptionType(this.c_bKey[], this.c_bIv[]);

//Class...

public class EncryptionType_TripleDES
{
    //Constructor...
    public EncryptionType_TripleDES(byte[] key, byte[] iv)
    {
        this.c_key = key;
        this.c_iv = iv;
    }
}

Thanks...

Since I can't edit the post, so here's the correction for the foo function...

public class EncryptionType_TripleDES
{
    //define the local property arrays
    private byte[] c_key;
    private byte[] c_iv;

    //Constructor...
    public EncryptionType_TripleDES(byte[] key, byte[] iv)
    {
        this.c_key = key;
        this.c_iv = iv;
    }
}

this line is the problem
private EncryptionType c_oEncryption = new EncryptionType(this.c_bKey[], this.c_bIv[]);
varible[] is invalid syntanx. it also doesn't work to initialize in the field, because the arrays are initialized there as well.

move this to ctor and you'll be fine

public class Foo
{
   private byte[] c_bKey = new byte[] { ... };
   private byte[] c_bIv = new byte[] { ... };
   private readonly EncryptionType c_oEncryption;
   
   public Foo()
   {
      c_oEncryption = new EncryptionType(c_bKey, c_bIv);
   }
}

I'm still getting the compiler error, it's a different one now...

It said "A field initializer cannot reference the non-static field, method, or property 'signin.c_bKey'"....

The "EncryptionType_TripleDES" is a class with it's own constructor but not the other sample code I posted cuz it's on an ASP.NET webpage... The "sigin" is the name of the class on the ASP.NET webpage...

 

[fletchsod]

Got it! Putting this "c_oEncryption = new EncryptionType(c_bKey, c_bIv);" into the Page_Load function does the trick.

Now I'm beginning to understand why I got this error. If you step through a call to a constructor of a class, you will see that all member variables are initialized before the constructor is invoked. So, trying to initialize this "blah = new EntryptionType(c_bKey, c_bIv);"

Invoked a property of the class, but the instance was still under construction, and so unable to return a value from that property.

 

[chiph]

Yup. Static variables get initialized first (as you'd expect, since they're shared amongst all instances), and then the instance variables get initialized, and then one of the constructors gets called.
