本編では最短パス解析と同様のサービスを使用
最短パスとの違い
    var closestFacilityTask = new ClosestFacilityTask("http://localhost:6080/arcgis/rest/services/webgis/fzkt_wlfx_all/NAServer/     ");
    var params = new ClosestFacilityParameters();

    params.impedenceAttribute = "Miles";
    params.defaultCutoff = 7.0;
    //       
    params.returnIncidents = false;
    //    
    params.returnRoutes = true;
    //     
    params.returnDirections = true;
    //   
    params.facilities = new FeatureSet();
    //   
    params.incidents = new FeatureSet();
    //

    //    
    params.outSpatialReference = map.SpatialReference;

基本アーキテクチャは最短パスと同じで、ここで直接コードを貼って、詳しくは最短パス分析を参照してください.
