DynamicMethod.DefineParameter Method
Defines a parameter of the dynamic method.
Assembly: mscorlib (in mscorlib.dll)
public ParameterBuilder DefineParameter( int position, ParameterAttributes attributes, string parameterName )
Parameters
- position
- Type: System.Int32
The position of the parameter in the parameter list. Parameters are indexed beginning with the number 1 for the first parameter.
- attributes
- Type: System.Reflection.ParameterAttributes
A bitwise combination of ParameterAttributes values that specifies the attributes of the parameter.
- parameterName
- Type: System.String
The name of the parameter. The name can be a zero-length string.
| Exception | Condition |

The method has no parameters. -or- position is less than 0. -or- position is greater than the number of the method's parameters. |
If position is 0, the DefineParameter method refers to the return value. Setting parameter information has no effect on the return value.
If the dynamic method has already been completed, by calling the CreateDelegate or Invoke method, the DefineParameter method has no effect. No exception is thrown.
The following code example shows how to define parameter information for a dynamic method. This code example is part of a larger example provided for the DynamicMethod class.
// Add parameter information to the dynamic method. (This is not // necessary, but can be useful for debugging.) For each parameter, // identified by position, supply the parameter attributes and a // parameter name. hello.DefineParameter(1, ParameterAttributes.In, "message"); hello.DefineParameter(2, ParameterAttributes.In, "valueToReturn");
