Assembly: System (in System.dll)
The DefaultValueAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
 | DefaultValueAttribute(Boolean) | Initializes a new instance of the DefaultValueAttribute class using a Boolean value. |
| DefaultValueAttribute(Byte) | Initializes a new instance of the DefaultValueAttribute class using an 8-bit unsigned integer. |
| DefaultValueAttribute(Char) | Initializes a new instance of the DefaultValueAttribute class using a Unicode character. |
| DefaultValueAttribute(Double) | Initializes a new instance of the DefaultValueAttribute class using a double-precision floating point number. |
| DefaultValueAttribute(Int16) | Initializes a new instance of the DefaultValueAttribute class using a 16-bit signed integer. |
| DefaultValueAttribute(Int32) | Initializes a new instance of the DefaultValueAttribute class using a 32-bit signed integer. |
| DefaultValueAttribute(Int64) | Initializes a new instance of the DefaultValueAttribute class using a 64-bit signed integer. |
| DefaultValueAttribute(Object) | Initializes a new instance of the DefaultValueAttribute class. |
| DefaultValueAttribute(Single) | Initializes a new instance of the DefaultValueAttribute class using a single-precision floating point number. |
| DefaultValueAttribute(String) | Initializes a new instance of the DefaultValueAttribute class using a String. |
| DefaultValueAttribute(Type, String) | Initializes a new instance of the DefaultValueAttribute class, converting the specified value to the specified type, and using an invariant culture as the translation context. |
| Name | Description | |
|---|---|---|
| Equals | Returns whether the value of the given object is equal to the current DefaultValueAttribute. (Overrides Attribute::Equals(Object).) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Returns the hash code for this instance. (Overrides Attribute::GetHashCode().) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| SetValue | Sets the default value for the property to which this attribute is bound. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
You can create a DefaultValueAttribute with any value. A member's default value is typically its initial value. A visual designer can use the default value to reset the member's value. Code generators can use the default values also to determine whether code should be generated for the member.
