Definition.GetDataType Method

DefinitionGetDataType Method

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
public ForgeTypeId GetDataType()
Public Function GetDataType As ForgeTypeId
public:
ForgeTypeId^ GetDataType()
member GetDataType : unit -> ForgeTypeId

Return Value

ForgeTypeId
A 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
Copy
//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;
}
'Find parameter using the Parameter's definition data type.
Public Function FindParameter(element As Element) As Parameter
    Dim foundParameter As Parameter = Nothing
    ' This will find the first parameter that measures length
    For Each parameter As Parameter In element.Parameters
        If parameter.Definition.GetDataType() = SpecTypeId.Length Then
            foundParameter = parameter
            Exit For
        End If
    Next
    Return foundParameter
End Function
