◆ TryBinaryOperation()

virtual bool System.Dynamic.DynamicObject.TryBinaryOperation	(	BinaryOperationBinder	binder,
		object	arg,
		out object	result
	)

virtual

Provides implementation for binary operations. Classes derived from the T:System.Dynamic.DynamicObject class can override this method to specify dynamic behavior for operations such as addition and multiplication.

Parameters

binder	Provides information about the binary operation. The binder.Operation property returns an T:System.Linq.Expressions.ExpressionType object. For example, for the sum = first + second statement, where first and second are derived from the `DynamicObject` class, binder.Operation returns ExpressionType.Add.
arg	The right operand for the binary operation. For example, for the sum = first + second statement, where first and second are derived from the `DynamicObject` class, arg is equal to second.
result	The result of the binary operation.

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

Definition at line 430 of file DynamicObject.cs.

◆ TryConvert()

virtual bool System.Dynamic.DynamicObject.TryConvert	(	ConvertBinder	binder,
		out object	result
	)

virtual

Provides implementation for type conversion operations. Classes derived from the T:System.Dynamic.DynamicObject class can override this method to specify dynamic behavior for operations that convert an object from one type to another.

Parameters

binder Provides information about the conversion operation. The binder.Type property provides the type to which the object must be converted. For example, for the statement (String)sampleObject in C# (CType(sampleObject, Type) in Visual Basic), where sampleObject is an instance of the class derived from the T:System.Dynamic.DynamicObject class, binder.Type returns the T:System.String type. The binder.Explicit property provides information about the kind of conversion that occurs. It returns true for explicit conversion and false for implicit conversion.

result The result of the type conversion operation.

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

◆ TryCreateInstance()

virtual bool System.Dynamic.DynamicObject.TryCreateInstance	(	CreateInstanceBinder	binder,
		object []	args,
		out object	result
	)

virtual

Provides the implementation for operations that initialize a new instance of a dynamic object. This method is not intended for use in C# or Visual Basic.

Parameters

binder	Provides information about the initialization operation.
args	The arguments that are passed to the object during initialization. For example, for the new SampleType(100) operation, where SampleType is the type derived from the T:System.Dynamic.DynamicObject class, args[0] is equal to 100.
result	The result of the initialization.

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

Parameters

binder	Provides information about the deletion.
indexes	The indexes to be deleted.

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.)

virtual bool System.Dynamic.DynamicObject.TryDeleteMember ( DeleteMemberBinder binder )

virtual

Provides the implementation for operations that delete an object member. This method is not intended for use in C# or Visual Basic.

◆ TryGetIndex()

virtual bool System.Dynamic.DynamicObject.TryGetIndex	(	GetIndexBinder	binder,

virtual

Provides the implementation for operations that get a value by index. Classes derived from the T:System.Dynamic.DynamicObject class can override this method to specify dynamic behavior for indexing operations.

Parameters

binder	Provides information about the operation.
indexes	The indexes that are used in the operation. For example, for the sampleObject[3] operation in C# (sampleObject(3) in Visual Basic), where sampleObject is derived from the `DynamicObject` class, indexes[0] is equal to 3.
result	The result of the index operation.

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a run-time exception is thrown.)

◆ TryGetMember()

virtual bool System.Dynamic.DynamicObject.TryGetMember	(	GetMemberBinder	binder,
		out object	result
	)

virtual

Provides the implementation for operations that get member values. Classes derived from the T:System.Dynamic.DynamicObject class can override this method to specify dynamic behavior for operations such as getting a value for a property.

Parameters

binder Provides information about the object that called the dynamic operation. The binder.Name property provides the name of the member on which the dynamic operation is performed. For example, for the Console.WriteLine(sampleObject.SampleProperty) statement, where sampleObject is an instance of the class derived from the T:System.Dynamic.DynamicObject class, binder.Name returns "SampleProperty". The binder.IgnoreCase property specifies whether the member name is case-sensitive.

result The result of the get operation. For example, if the method is called for a property, you can assign the property value to result .

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a run-time exception is thrown.)

◆ TryInvoke()

virtual bool System.Dynamic.DynamicObject.TryInvoke	(	InvokeBinder	binder,
		object []	args,

Returns: true if the operation is successful; otherwise, false. If this method returns false, the run-time binder of the language determines the behavior. (In most cases, a language-specific run-time exception is thrown.

For example, for the statement sampleObject.SampleMethod(100), where sampleObject is an instance of the class derived from the T:System.Dynamic.DynamicObject class, binder.Name returns "SampleMethod". The binder.IgnoreCase property specifies whether the member name is case-sensitive.
