Gedcom Reader for C#

Question

Does anyone know of a good class to read in .ged files

Gedcom is a file format that is used to store genealogical information.

My goal is to write something that would let me import a ged file and export a .dot file for graphviz so that I can make a visual representation of a family tree

thanks if you can help

Answer 1

Heres my best attempt so far.

It seems to be working for what i need though its defiently not full proof ( then again my family tree is rather large and that adds some complexity)

please let me know if you think i could make anything more elequient

struct INDI
        {
            public string ID;
            public string Name;
            public string Sex;
            public string BirthDay;
            public bool Dead;


        }
        struct FAM
        {
            public string FamID;
            public string type;
            public string IndiID;
        }
        List<INDI> Individuals = new List<INDI>();
        List<FAM> Family = new List<FAM>();
        private void button1_Click(object sender, EventArgs e)
        {
            string path = @"C:\mostrecent.ged";
            ParseGedcom(path);
        }

        private void ParseGedcom(string path)
        {
            //Open path to GED file
            StreamReader SR = new StreamReader(path);

            //Read entire block and then plit on 0 @ for individuals and familys (no other info is needed for this instance)
            string[] Holder = SR.ReadToEnd().Replace("0 @", "\u0646").Split('\u0646');

            //For each new cell in the holder array look for Individuals and familys
            foreach (string Node in Holder)
            {

                //Sub Split the string on the returns to get a true block of info
                string[] SubNode = Node.Replace("\r\n", "\r").Split('\r');
                //If a individual is found
                if (SubNode[0].Contains("INDI"))
                {

                    }

                    // deterimin if there is a death tag will return -1 if not found

                    {
                        //convert Y or N to true or false ( defaults to False so no need to change unless Y is found.
                        if (SubNode[FindIndexinArray(SubNode, "1 DEAT ")].Replace("1 DEAT ", "").Trim() == "Y")
                        {

                    string FamID = SubNode[0].Replace("@ FAM", "");

                    // Multiple children can exist for each family so this section had to be a bit more dynaimic

                    // Look at each line of node

Answer 2

There is a very pretty one at Codeplex: FamilyShow (a WPF showcase). It imports/exports GEDCOM 5.5 and there is source.
