Contains meta-information on an individual property within the configuration. This type cannot be inherited.
Assembly: System.Configuration (in System.Configuration.dll)
| Name | Description | |

![]() | Converter | Gets the TypeConverter object related to the configuration attribute. |
![]() | DefaultValue | Gets an object containing the default value related to a configuration attribute. |
![]() | Description | Gets the description of the object that corresponds to a configuration attribute. |
![]() | IsKey | Gets a value specifying whether the configuration attribute is a key. |
![]() | IsLocked | Gets a value specifying whether the configuration attribute is locked. |
![]() | IsModified | Gets a value specifying whether the configuration attribute has been modified. |
![]() | IsRequired | Gets a value specifying whether the configuration attribute is required. |
![]() | LineNumber | Gets the line number in the configuration file related to the configuration attribute. |
![]() | Name | Gets the name of the object that corresponds to a configuration attribute. |
![]() | Source | Gets the source file that corresponds to a configuration attribute. |
![]() | Type | Gets the Type of the object that corresponds to a configuration attribute. |
![]() | Validator | Gets a ConfigurationValidatorBase object related to the configuration attribute. |
![]() | Value | Gets or sets an object containing the value related to a configuration attribute. |
![]() | ValueOrigin | Gets a PropertyValueOrigin object related to the configuration attribute. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
The PropertyInformation object contains the meta-information of an individual property within the configuration. This object can be used when validating and changing the properties of an individual attribute.
The PropertyInformation object is derived from the associated PropertyInformationCollection object. The PropertyInformationCollection object is derived from the associated ElementInformation object.
The following code example demonstrates how to use the PropertyInformation type.
