 | PasswordPropertyTextAttribute() | Initializes a new instance of the PasswordPropertyTextAttribute class. |
| PasswordPropertyTextAttribute(Boolean) | Initializes a new instance of the PasswordPropertyTextAttribute class, optionally showing password text. |
| Name | Description | |
|---|---|---|
| Equals | Determines whether two PasswordPropertyTextAttribute instances are equal. (Overrides Attribute.Equals(Object).) |
| GetHashCode | Returns the hash code for this instance. (Overrides Attribute.GetHashCode().) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsDefaultAttribute | Returns an indication whether the value of this instance is the default value. (Overrides Attribute.IsDefaultAttribute().) |
| Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |

| Yes | Specifies that a text property is used as a password. This static (Shared in Visual Basic) field is read-only. |
| Name | Description | |
|---|---|---|
| _Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
| _Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
| _Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
| _Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |

The following code example demonstrates using the PasswordPropertyTextAttribute to obscure the value of a string property in a PropertyGrid control. For a full code listing, see How to: Apply Attributes in Windows Forms Controls.
// This property exists only to demonstrate the // PasswordPropertyText attribute. When this control // is attached to a PropertyGrid control, the returned // string will be displayed with obscuring characters // such as asterisks. This property has no other effect. [Category("Security")] [Description("Demonstrates PasswordPropertyTextAttribute.")] [PasswordPropertyText(true)] public string Password { get { return "This is a demo password."; } }
