Cannot implicitly convert type 'System.Array' to 'string[]' in windows form

Question

I have a function (function1) in my winforms app(c#) that return an array

inside the function1

public array function1(string value)
{
string[] array = new string[12];
     //assigning values to the array elements....
retrun array;
}

and i call this function like this

string id="Some id";
string[] array2 = new string[12];
array2=this.function1(id);

but it gives me error

Cannot implicitly convert type 'System.Array' to 'string[]'. An explicit conversion exists (are you missing a cast?)

please experts help me !

Answer 1

Change

public array function1(string value)

to

public string[] function1(string value)

And in your example of usage, you do not need to initialize your array to new string[12] before hand, as your function returns a new array anyway.

Answer 2

The signature of function1 should be public string[] function1(string value) . The return type array doesn't match the variable of type string[]

Answer 3

This works, but not sure what the problem is:

public Form1()
{
    InitializeComponent();
    string id = "Some id"; 
    string[] array2 = new string[12]; 
    array2 = this.function1(id);
}

public string[] function1(string value)
{
    string[] array = new string[12];
    array[0] = value; // for example
    return array;
}
