示例1: Read

        public bool Read(IGraph myGraph, FileStream myInputStream)
        {
            // use a streamreader .. better handling
            StreamReader reader = null;
            // stores the added vertices for fast retrieval
            var addedVertices = new Dictionary<string, IVertex>();

            try
            {
                reader = new StreamReader(myInputStream);
                String line;    // current line in file
                String[] edge;  // contains source and target vertex id
                IVertex source; // source vertex
                IVertex target; // target vertex
                var count = 0L; // number of processed edges

                while ((line = reader.ReadLine()) != null)
                {
                    if (!line.StartsWith(EdgeListTokens.LINE_COMMENT)) // just a comment
                    {
                        // line look like that "0   1", splitting it to get source and target id
                        edge = line.Split(EdgeListTokens.SOURCE_TARGET_SEPARATOR);

                        // got two id's?
                        if (edge.Length == 2)
                        {
                            // check if source has been added before
                            if (!addedVertices.TryGetValue(edge[0], out source))
