member this.DefineProperty : string * System.Reflection.PropertyAttributes * Type * Type[] -> System.Reflection.Emit.PropertyBuilder

Public Function DefineProperty (name As String, attributes As PropertyAttributes, returnType As Type, parameterTypes As Type()) As PropertyBuilder

Parameters

name: String

The name of the property. name cannot contain embedded nulls.

attributes: PropertyAttributes

The attributes of the property.

returnType: Type

The return type of the property.

parameterTypes: Type[]

The types of the parameters of the property.

Returns

PropertyBuilder

The defined property.

Exceptions

ArgumentException

The length of name is zero.

ArgumentNullException

name is null.

-or-

Any of the elements of the parameterTypes array is null.

InvalidOperationException

The type was previously created using CreateType().

Examples

The following code sample demonstrates how to define a dynamic property and obtain a PropertyBuilder for specification. Note that a PropertyBuilder must also have a corresponding MethodBuilder, which will house the IL logic for the property.

If none of the parameters have required custom modifiers, specify null instead of an array of arrays.

parameterTypeOptionalCustomModifiers: Type[][]

An array of arrays of types. Each array of types represents the optional custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no optional custom modifiers, specify null instead of an array of types. If none of the parameters have optional custom modifiers, specify null instead of an array of arrays.

Returns

PropertyBuilder

The defined property.

Exceptions

ArgumentException

The length of name is zero.

ArgumentNullException

name is null

-or-

Any of the elements of the parameterTypes array is null

InvalidOperationException

The type was previously created using CreateType().

Remarks

This overload is provided for designers of managed compilers.

Note

For more information on custom modifiers, see ECMA C# and Common Language Infrastructure Standards and Standard ECMA-335 - Common Language Infrastructure (CLI).
