Import a From-to List Example (C#)

//--------------------------------------------------------------------------
// Preconditions:
// 1. Add SOLIDWORKS Routing as an add-in
//    (in SOLIDWORKS, select Tools > Add-Ins > SOLIDWORKS Routing).
// 2. Add SolidWorks.Interop.SwRoutingLib.dll as a reference
//    (in the IDE right-click the project,
//    select Add Reference, and browse install_dir\api\redist\CLR2).
// 3. In Tools > Options > System Options > Routing > Routing File Locations,
//    add locations of your SOLIDWORKS Routing files.
// 4. Open:
//    install_dir\samples\tutorial\routing\electrical\top_assy.sldasm.
// 5. Rename the namespace to match the name of your C# project.
// 6. Ensure that the specified files exist.
// 7. Open an Immediate Window.
//
// Postconditions:
// 1. Position the components in the harness by clicking the housing wall
//    five (5) times.
// 2. Click Yes in the message box.
// 3. Click the green checkmark in Route Properties to accept the defaults.
//    Guidelines display in the electronic housing.
//    The Auto Route PropertyManager page displays.
// 4. Click the green checkmark to accept the defaults.
// 5. Stop editing the route.
// 6. Stop editing the assembly.
// 7. Harness_1-top_assy, containing the imported route,
//    appears in the FeatureManager design tree.
//
// NOTE: Because the assembly is used elsewhere,
// do not save any changes when you close it.
