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))
{
// if not, create new vertex
source = myGraph.AddVertex(edge[0]);
addedVertices.Add(edge[0], source);
}
// check if target has been added before
if (!addedVertices.TryGetValue(edge[1], out target))
{
// if not, create new vertex
target = myGraph.AddVertex(edge[1]);
addedVertices.Add(edge[1], target);
}
if (myGraph.AddEdge(source, target) != null)
{
count++;
}
}
}
}
}
catch (IOException ex)
{
// TODO add logging here
return false;
}
finally
{
reader.Close();
