Deserialize lists within a .dat file to a text box using b formatter

Question

I have created an application that will save lists to a .dat file using a binary formatter and serializing the list.

I wish to then de serialize this list and display this within a text box.

Furthermore, I have tried using a for each loop to get every object from the list, but it won't continue through the rest of the lists and stops at the first list stored within the file.

I have been tasked with binary formatter even though Ive been informed its obsolete.

Answer 1

give this a try:

var totalList = new List<InPerson>();
do
{
    var subList = (List<InPerson>)bFormatter.Deserialize(inFile);
    totalList.AddRange(subList);
} while (!inFile.EndOfStream);

foreach (InPerson a in totalList)
    txtBookings.Text += a.ToString();

//maybe set InPersonLIst to totalList
InPersonList = totalList;

This assumes that instead of 1 list with many items, there are many lists with many items.

This structure seems odd to say the least, you should consider having 1 list with many items.
