Re: How I can iterate data in structure

[bearophile via Digitalmars-d-learn]

Suliman:

void main()
{
        
        auto result = readconfig();

        foreach (_; result)
        {
                // I want to iterate result that I got from structure.
        }
}

auto readconfig()
{
        struct ConfigStruct
        {
                string key1;
                string key2;
        }

        ConfigStruct confstruct = ConfigStruct();
        confstruct.key1="Ivan";
        confstruct.key2="admin";

        return confstruct;

}

Be careful to make ConfigStruct a static struct.

auto readconfig() {
    static struct ConfigStruct {
        string key1, key2;
    }

    return ConfigStruct("Ivan", "admin");
}

void main() {
    import std.stdio;
    auto result = readconfig();

    foreach (field; result.tupleof) {
        writeln(field);
    }
}
