Syntax

C#
public void Set<FieldType>(
	string fieldName,
	FieldType value,
	DisplayUnitType displayUnits
)
Visual Basic
Public Sub Set(Of FieldType) ( _
	fieldName As String, _
	value As FieldType, _
	displayUnits As DisplayUnitType _
)
Visual C++
public:
generic<typename FieldType>
void Set(
	String^ fieldName, 
	FieldType value, 
	DisplayUnitType displayUnits
)

Parameters

fieldName
Type: System..::..String
The name of the field to update.
value
Type: FieldType
displayUnits
Type: Autodesk.Revit.DB..::..DisplayUnitType
The units from which the value will be converted before storing. Must match the UnitType specified when creating the Schema.

Type Parameters

FieldType
The type of the field

Remarks

The template parameter must match the type of the field (specified when creating the Schema) exactly; no conversions will be performed inside this method (but may be performed on the returned value). The types for containers are IList for arrays and IDictionary for maps.

This method only modifies your copy of the Entity. Store the Entity in an element or another Entity to save the new value. Write access check is not performed on each call to Set. Instead, write access is checked when you try to save the Entity in an Element or another Entity.

This method is a shortcut that will look up the field by name. If you want to call it on many entities, it is faster if you look up the field yourself.
