SyntaxThe HostFunctions type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | HostFunctions | Initializes a new HostFunctions instance. |
Methods| Name | Description | |
|---|---|---|
 | asTypeT | Casts an object to the specified host type, returning null if the cast fails. |
| castT | Casts an object to the specified host type. |
| delT | Creates a delegate that invokes a script function. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| flagsT | Creates a strongly typed flag set. |
| func(Int32, Object) | Creates a delegate that invokes a script function and returns its result value. |
| funcT(Int32, Object) | Creates a delegate that invokes a script function and returns a value of the specified type. |
| getElement | Gets the value of an element in a dynamic host object that implements IDynamicMetaObjectProvider. |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| getProperty(IDynamicMetaObjectProvider, String) | Gets the value of a property in a dynamic host object that implements IDynamicMetaObjectProvider. |
| getProperty(IPropertyBag, String) | Gets the value of a property in a dynamic host object that implements IPropertyBag. |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| isNull | Determines whether the specified value is null. |
| isTypeT | Determines whether an object is compatible with the specified host type. |
| isTypeObj(Object) | Determines whether an object is a host type. This version is invoked if the specified object cannot be used as a type argument. |
| isTypeObjT | Determines whether an object is a host type. This version is invoked if the specified object can be used as a type argument. |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| newArr(Int32) | Creates a host array with Object as the element type. |
| newArrT(Int32) | Creates a host array with the specified element type. |
| newObj | Creates an empty host object. |
| newObj(IDynamicMetaObjectProvider, Object) | Performs dynamic instantiation. |
| newObj(Object, Object) | Creates a host object of the specified type. This version is invoked if the specified type cannot be used as a type argument. |
| newObjT(Object) | Creates a host object of the specified type. This version is invoked if the specified type can be used as a type argument. |
| newVarT | Creates a host variable of the specified type. |
| proc | Creates a delegate that invokes a script function and returns no value. |
| removeElement | Removes an element from a dynamic host object that implements IDynamicMetaObjectProvider. |
| removeProperty(IDynamicMetaObjectProvider, String) | Removes a property from a dynamic host object that implements IDynamicMetaObjectProvider. |
| removeProperty(IPropertyBag, String) | Removes a property from a dynamic host object that implements IPropertyBag. |
| setElement | Sets an element value in a dynamic host object that implements IDynamicMetaObjectProvider. |
| setProperty(IDynamicMetaObjectProvider, String, Object) | Sets a property value in a dynamic host object that implements IDynamicMetaObjectProvider. |
| setProperty(IPropertyBag, String, Object) | Sets a property value in a dynamic host object that implements IPropertyBag. |
| toByte | Converts the specified value to a strongly typed Byte instance. |
| toChar | Converts the specified value to a strongly typed Char instance. |
| toDecimal | Converts the specified value to a strongly typed Decimal instance. |
| toDouble | Converts the specified value to a strongly typed Double instance. |
| toInt16 | Converts the specified value to a strongly typed Int16 instance. |
| toInt32 | Converts the specified value to a strongly typed Int32 instance. |
| toInt64 | Converts the specified value to a strongly typed Int64 instance. |
| toSByte | Converts the specified value to a strongly typed SByte instance. |
| toSingle | Converts the specified value to a strongly typed Single instance. |
| toStaticType | Casts a dynamic host object to its static type. |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
| toUInt16 | Converts the specified value to a strongly typed UInt16 instance. |
| toUInt32 | Converts the specified value to a strongly typed UInt32 instance. |
| toUInt64 | Converts the specified value to a strongly typed UInt64 instance. |
| tryCatch | Allows script code to handle host exceptions. |
| typeOf(Object) | Gets the Type for the specified host type. This version is invoked if the specified object cannot be used as a type argument. |
| typeOfT | Gets the Type for the specified host type. This version is invoked if the specified object can be used as a type argument. |
Remarks
Use AddHostObject to expose a
HostFunctions instance to script code. Each instance can only be exposed in one
script engine.
