For loop variable scope

[rovercoder]

It seems that variables inside for loops are not being scoped correctly. The index per iteration is lost for either bind or onchange, but appears correctly when printed out as HTML. No matter what I do I always get the final index value (PlayerCount = 2 produces an i = 3 for both entries).

1. Using onchange method

@for (int i = 1; i <= PlayerCount; i++)
{
    <text>Player </text>@i <input type="text" onchange=@(e => WritePlayerName(i, e)) /><br />
}

@functions{
    [Parameter] int PlayerCount { get; set; } 
    void WritePlayerName(int playerNo, UIChangeEventArgs ev)
    {
        Console.WriteLine(playerNo + " " + ev.Value.ToString());
    }
}

Results

3 Andy
3 John

2. Binding array element

@for (int i = 1; i <= PlayerCount; i++)
{
    <text>Player </text>@i <input type="text" bind=@playerNames[i-1] /><br />
}

@functions{
    [Parameter] int PlayerCount { get; set; }
    string[] playerNames;
    protected override void OnParametersSet()
    {
        playerNames = new string[PlayerCount];
    }
}

Am I missing something? Is there a better way?

Look at aspnet/Blazor#1402
