TypeUsage Class
.NET Framework 4.5
Describes a type and a set of facets for that type.
Namespace: System.Data.Metadata.Edm
Assembly: System.Data.Entity (in System.Data.Entity.dll)
The TypeUsage type exposes the following members.
| Name | Description | |
|---|---|---|
 | BuiltInTypeKind | Gets the built-in type kind for this TypeUsage. (Overrides MetadataItem.BuiltInTypeKind.) |
| Documentation | Gets or sets the documentation associated with this type. (Inherited from MetadataItem.) |
| EdmType | Gets the type information described by this TypeUsage. |
| Facets | Gets the list of facets for the type that is described by this TypeUsage. |
| MetadataProperties | Gets the list of properties of the current type. (Inherited from MetadataItem.) |
| Name | Description | |
|---|---|---|
  | CreateBinaryTypeUsage(PrimitiveType, Boolean) | Creates a TypeUsage object to describe a binary type by using the specified facet values. |
| CreateBinaryTypeUsage(PrimitiveType, Boolean, Int32) | Creates a TypeUsage object to describe a binary type by using the specified facet values. |
| CreateDateTimeOffsetTypeUsage | Creates a DateTimeOffsetTypeUsage object of the type that the parameters describe. |
| CreateDateTimeTypeUsage | Creates a DateTimeTypeUsage object of the type that the parameters describe. |
| CreateDecimalTypeUsage(PrimitiveType) | Creates a TypeUsage object to describe a decimal type with unbounded precision and scale facet values. |
| CreateDecimalTypeUsage(PrimitiveType, Byte, Byte) | Creates a TypeUsage object to describe a decimal type by using the specified facet values. |
| CreateDefaultTypeUsage | Creates a TypeUsage object with the specified conceptual model type. |
| CreateStringTypeUsage(PrimitiveType, Boolean, Boolean) | Creates a TypeUsage object to describe a string type by using the specified facet values and unbounded MaxLength. |
| CreateStringTypeUsage(PrimitiveType, Boolean, Boolean, Int32) | Creates a TypeUsage object to describe a string type by using the specified facet values. |
| CreateTimeTypeUsage | Creates a TimeTypeUsage object of the type that the parameters describe. |
| Equals(Object) | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsSubtypeOf | Checks whether this TypeUsage is a subtype of the specified TypeUsage. |
| ToString | Returns the full name of the type described by this TypeUsage. (Overrides Object.ToString().) |
| Name | Description | |
|---|---|---|
 | Constant | Creates a new DbConstantExpression of the specified primitive type with the given constant value. (Defined by DbExpressionBuilder.) |
| New(DbExpression[]) | Overloaded. Creates a new DbNewInstanceExpression. If the type argument is a collection type, the arguments specify the elements of the collection. Otherwise the arguments are used as property or column values in the new instance. (Defined by DbExpressionBuilder.) |
| New(IEnumerable<DbExpression>) | Overloaded. Creates a new DbNewInstanceExpression. If the type argument is a collection type, the arguments specify the elements of the collection. Otherwise the arguments are used as property or column values in the new instance. (Defined by DbExpressionBuilder.) |
| NewEmptyCollection | Creates a new DbNewInstanceExpression that constructs an empty collection of the specified collection type. (Defined by DbExpressionBuilder.) |
| Null | Creates a new DbNullExpression, which represents a typed null value. (Defined by DbExpressionBuilder.) |
| Parameter | Creates a new DbParameterReferenceExpression that references a parameter with the specified name and type. (Defined by DbExpressionBuilder.) |
| Variable | Creates a new DbVariableReferenceExpression that references a variable with the specified name and type. (Defined by DbExpressionBuilder.) |
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
