GetLength
unsigned int GetLength();
Returns the length if the CDocBuilderValue object is an array/typed array. Otherwise, returns 0.
Please note, that for the .docbuilder file the CDocBuilderValue.GetLength method is not used.
Example
.Net
string workDirectory = "C:/Program Files/ONLYOFFICE/DocumentBuilder";
CDocBuilder.Initialize(workDirectory);
CDocBuilder oBuilder = new CDocBuilder();
CContext oContext = oBuilder.GetContext();
CValue oGlobal = oContext.GetGlobal();
CValue oApi = oGlobal["Api"];
CValue oDocument = oApi.Call("GetDocument");
CValue aCharts = oDocument.Call("GetAllCharts");
unsigned int nLength = aCharts.GetLength();
CDocBuilder.Destroy();
