Remarks
A geography level is selected using the BranchID and Depth parameters. The BranchID specifies a branch of the tree of standard geography levels (e.g. "USbyTracts", "USbyCounties", or "USbyZIP5") and the Depth specifies the geography level depth for the given branch (e.g. the level depth in "USbyZIP5" branch is 0 for whole USA, 1 for States, 2 for Counties, and 3 for ZIPs).
The Criterion and IDCriterion parameters specify the criteria for search in locations' name and ID fields, respectively. If both criteria are specified, the geography locations are searched in the standard geography level using the logical AND operation. If both criteria are missing, all locations of the standard geography level are queried. The returned feature list represents the complete list of children of all matching locations from the specified geography level.

|---|---|
StdGeographiesFromTreeParameters parameters = new StdGeographiesFromTreeParameters(); // Set an ID of branch in the tree of standard geography levels. parameters.BranchID = "USbyZIP5"; // Set a depth of the geography level in the given branch. This is the US Counties level. parameters.Depth = 2; // Set a string to search in names of geography locations. This is the San Diego County. parameters.Criterion = "San Diego"; // Execute the task. The result will be a list of all ZIP5 codes of the San Diego County. stdGeographiesFromTreeTask.ExecuteAsync(parameters, new AsyncResponder(resultHandler, faultHandler)); | |
