Cannot implicitly convert type 'System.Collections.Generic.IEnumerable<string> to string

Question

i have the code:

    public HomePage1()
    {
        InitializeComponent();
        LoadExcelFile loader = new LoadExcelFile();
        loader.ReadAndParse();            
        Title = "Home Page";
        StackLayout layout = new StackLayout();
        layout.Children.Add(new Image() { Source = "@drawable/img" });


        foreach (Block block in loader.Blocks)
        {
            switch (block.Title.ToLower())
            {
                case "hp-int":                        
                    layout.Children.Add(new Label(){Text=**block.Content**});
                    break;
                default:
                    //layout.Children.Add(new Label() { Text = block.Content });
                    break;
            }


        }

        Content = layout;

I want show in a label the text it's in block.content with title "hp-int" but appears the error "Cannot implicitly convert type 'System.Collections.Generic.IEnumerable to string". if i choose the title works fine, but the content...

Can help me?? thanks

How does the Block class look like? What is the type of the Content property? What does it contain? — Yacoub Massad
the block like: public IEnumerable<Block> Blocks { get; set; } (block.Content as List<string>).Add(item.Groups["blockContent"].Value.Trim()); i just want show the content when the title is "some tag"; when layout.children.add (new Label(){Text=block.Content}); show the error... — Pedro Silva

If the Content property is a list of strings, then you have to combine them in one string, e.g.

layout.Children.Add(new Label(){Text= block.Content.Aggregate((a, b) => a + b) });

As suggested by @Charles Mager this would perform better:

layout.Children.Add(new Label(){Text= string.Concat(block.Content) });
