Question

I have the following function:

public string GetRaumImageName()
    {
         var md5 = System.Security.Cryptography.MD5.Create();
        byte[] hash = md5.ComputeHash(Encoding.ASCII.GetBytes("Michael"));
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("X2"));
        }
        return sb.ToString();
    }

This works fine with just one value.

Now i want to encrypt multiple values. I tried something:

public string GetRaumImageName()
    {
        var md5 = System.Security.Cryptography.MD5.Create();
        StringBuilder sb = new StringBuilder();
        byte[] hash = new byte[0];

        foreach (PanelView panelView in pv)
        {
            hash = md5.ComputeHash(Encoding.ASCII.GetBytes(panelView.Title));

        }

        for (int i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("X2"));

        }

        return sb.ToString();
    }

But only the last Value in the list in getting encrypt. How can i encrypt multiples values which are in a list and return them?

Answer 1

    public IEnumerable<String> GetRaumImageName()
    {
        var md5 = System.Security.Cryptography.MD5.Create();

        byte[] hash = new byte[0];

        foreach (PanelView panelView in pv)
        {
            hash = md5.ComputeHash(Encoding.ASCII.GetBytes(panelView.Title));
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < hash.Length; i++)
            {
                sb.Append(hash[i].ToString("X2"));

            }
            yield return sb.ToString();
        }          
    }

This will return all the Values u need as IEnumerable<String>

Typical usage

var values = GetRaumImageName();
foreach(value in values)
{
    // use the 'value'
}
