Definition Get |
Gets a ForgeTypeId identifying the data type describing values of the parameter.
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax Return Value
ForgeTypeIdA ForgeTypeId identifying the data type of the parameter or an empty ForgeTypeId.
Remarks The returned ForgeTypeId may be empty or may identify either a spec or a category. When it is a category, it indicates a Family Type parameter of that category. See Parameter.IsSpec(ForgeTypeId), UnitUtils.IsMeasurableSpec(ForgeTypeId), Category.IsBuiltInCategory(ForgeTypeId), and Parameter.IsValidDataType(ForgeTypeId). Some built-in parameters, such as those for color or level, have special data types which are not available for use with user-defined parameters and which have no representation in the Revit user interface or API. For these built-in parameters, this method returns an empty ForgeTypeId instance.
Example //Find parameter using the Parameter's definition data type.
public Parameter FindParameter(Element element)
{
Parameter foundParameter = null;
// This will find the first parameter that measures length
foreach (Parameter parameter in element.Parameters)
{
if (parameter.Definition.GetDataType() == SpecTypeId.Length)
{
foundParameter = parameter;
break;
}
}
return foundParameter;
