ParameterInfo.DefaultValue Property

Definition

Gets a value indicating the default value if the parameter has a default value.

public virtual object DefaultValue { get; }
public virtual object? DefaultValue { get; }

Property Value

The default value of the parameter, or Value if the parameter has no default value.

Remarks

This property is used only in the execution context. In the reflection-only context, use the RawDefaultValue property instead.

The default value is used when an actual value is not specified in the method call. A parameter can have a default value that is null. This is distinct from the case where a default value is not defined.

This method utilizes the DefaultValueImpl method.

To get the ParameterInfo array, first get the method or the constructor and then call MethodBase.GetParameters.
