Assembly: mscorlib (in mscorlib.dll)
Parameters
- defaultValue
- Type: System.Object
The default value of this parameter.
| Exception | Condition |
|---|---|
| ArgumentException | The parameter is not one of the supported types. -or- The type of defaultValue does not match the type of the parameter. -or- The parameter is of type Object or other reference type, defaultValue is not Nothing, and the value cannot be assigned to the reference type. |
defaultValue is restricted to the following types: Boolean, SByte, Int16, Int32, Int64, Byte, UInt16, UInt32, UInt64, Single, Double, DateTime, Char, String, and Enum. If the parameter type is a reference type, CLS compliance requires defaultValue to be Nothing. However, starting with Windows Phone OS 7.1, defaultValue can be non-null for a reference type as long as the value can be assigned to that reference type. For example, an Int32 value can be assigned to a parameter of type Object. This is not CLS-compliant, but it can be useful in interop scenarios.
