Remarks

The DDGCStreetSearcher object belonging to a DrillDownGeoCoder instance can be obtained by calling the DrillDownGeoCoder.GetStreetSearcher() method.

Caution note Caution
If the parent DrillDownGeoCoder is disposed of, the DDGCStreetSearcher will cease to function correctly.

The set of streets searched will be limited to the regions set on the parent DrillDownGeoCoder. When the ChangeSearchTerm(String) method is called, a new search will begin; when this search is complete, the OnFoundResults event will fire. If a new search term is entered before the previous search has completed, the previous search will be aborted.

Examples
C#
Copy
public void DDGCDemo() {
    DrillDownGeoCoder ddgc = new DrillDownGeoCoder(Country.USA);

    // Assume we have set the following regions:
    // Region 0 - California
    // Region 1 - Orange
    // Region 2 - Aliso Viejo

    DDGCStreetSearcher streetSearch = ddgc.GetStreetSearcher();
    streetSearch.OnFoundResults += new Action<StreetSearchResult>(streetSearch_OnFoundResults);
    streetSearch.ChangeSearchTerm("Enterprise");
}

void streetSearch_OnFoundResults(StreetSearchResult obj) {
    if (obj.Status != SearchResult.Searching) {
        foreach (StreetData sd in obj.Results) {
            Console.WriteLine(sd.CollatedName);
        }
    }
}

// Output:
// Enterprise
// Enterprise Ct/Way
