Increase the cost of this link by the specified amount.

Namespace:  Telogis.GeoBase.Routing
Assembly:  geobase.net (in geobase.net.dll) Version: 4.99.0.0
Syntax
Copy
public void addCost(
	int cost
)

Parameters

cost
Type: SystemInt32
The amount to increase or reduce the link cost by.
Remarks
Using this method you can also decrease the cost of traveling the link, for example:
Copy
// suppose lc is some LinkCost given to us...

Console.WriteLine(lc.Cost); // outputs 60 -- so our link has a cost of 60

if ( /* we decide to reduce cost by 100, arbitrarily */ ) {
    lc.addCost(-100);
    Console.WriteLine("Decreased by 100, new cost:" + lc.Cost);
    // ^^ outputs 1 -- GeoBase has forced the cost to remain >= 1
}

else { /* we decide to increase cost */
    lc.addCost(300);
    Console.WriteLine("Increased by 300, new cost:" + lc.Cost);
    // ^^ outputs 360
}

Because negative link costs are nonsensical GeoBase will never let the cost for a link drop below 1.

If you'd like to strongly discourage GeoBase from routing along a particular link use the UndesirableLink property. Use of this property is preferable to setting a high link cost using the addCost(int cost) method.

If you'd like to prevent GeoBase from routing along a particular link use the ProhibitedLink property.
