C# function to return array

/// <summary>
/// Returns an array of all ArtworkData filtered by User ID
/// </summary>
/// <param name="UsersID">User ID to filter on</param>
/// <returns></returns>
public static Array[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels[];
}

I get a syntax error, ; expected after return Labels[].

Am I doing t开发者_JAVA技巧his right?

You're trying to return variable Labels of type ArtworkData instead of array, therefore this needs to be in the method signature as its return type. You need to modify your code as such:

public static ArtworkData[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels;
}

Array[] is actually an array of Array, if that makes sense.

return Labels; should do the trick!

public static ArtworkData[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels;
}

public static ArtworkData[] GetDataRecords(int UsersID)
{
    ArtworkData[] Labels;
    Labels = new ArtworkData[3];

    return Labels;
}

This should work.

You only use the brackets when creating an array or accessing an array. Also, Array[] is returning an array of array. You need to return the typed array ArtworkData[].

Two changes are needed:

1. Change the return type of the method from Array[] to ArtWorkData[]
2. Change Labels[] in the return statement to Labels

You should return the variable withouth the brackets

Return Labels

 static void Main()
     {
             for (int i=0; i<GetNames().Length; i++)
               {
                    Console.WriteLine (GetNames()[i]);
                }
     }

  static string[] GetNames()
   {
         string[] ret = {"Answer", "by", "Anonymous", "Pakistani"};
         return ret;
   }
