Represents a single, named connection string in the connection strings configuration file section.
System.Configuration.ConfigurationElement
System.Configuration.ConnectionStringSettings
Namespace: System.Configuration
Assembly: System.Configuration (in System.Configuration.dll)
The ConnectionStringSettings type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ConnectionStringSettings | Initializes a new instance of a ConnectionStringSettings class. |
![]() | ConnectionStringSettings(String, String) | Initializes a new instance of a ConnectionStringSettings class. |
![]() | ConnectionStringSettings(String, String, String) | Initializes a new instance of a ConnectionStringSettings object. |
| Name | Description | |
|---|---|---|
![]() | ConnectionString | Gets or sets the connection string. |
![]() | CurrentConfiguration | Gets a reference to the top-level Configuration instance that represents the configuration hierarchy that the current ConfigurationElement instance belongs to. (Inherited from ConfigurationElement.) |
![]() | ElementInformation | Gets an ElementInformation object that contains the non-customizable information and functionality of the ConfigurationElement object. (Inherited from ConfigurationElement.) |
![]() | ElementProperty | Gets the ConfigurationElementProperty object that represents the ConfigurationElement object itself. (Inherited from ConfigurationElement.) |
![]() | Item(ConfigurationProperty) | Gets or sets a property or attribute of this configuration element. (Inherited from ConfigurationElement.) |
![]() | Item(String) | Gets or sets a property, attribute, or child element of this configuration element. (Inherited from ConfigurationElement.) |
![]() | LockAllAttributesExcept | Gets the collection of locked attributes. (Inherited from ConfigurationElement.) |
![]() | LockAllElementsExcept | Gets the collection of locked elements. (Inherited from ConfigurationElement.) |
![]() | LockAttributes | Gets the collection of locked attributes (Inherited from ConfigurationElement.) |
![]() | LockElements | Gets the collection of locked elements. (Inherited from ConfigurationElement.) |
![]() | LockItem | Gets or sets a value indicating whether the element is locked. (Inherited from ConfigurationElement.) |
![]() | Name | Gets or sets the ConnectionStringSettings name. |
![]() | Properties | Gets the collection of properties. (Inherited from ConfigurationElement.) |
![]() | ProviderName | Gets or sets the provider name property. |
| Name | Description | |
|---|---|---|
![]() | DeserializeElement | Reads XML from the configuration file. (Inherited from ConfigurationElement.) |
![]() | Equals | Compares the current ConfigurationElement instance to the specified object. (Inherited from ConfigurationElement.) |
![]() | GetHashCode | Gets a unique value representing the current ConfigurationElement instance. (Inherited from ConfigurationElement.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | Init | Sets the ConfigurationElement object to its initial state. (Inherited from ConfigurationElement.) |
![]() | InitializeDefault | Used to initialize a default set of values for the ConfigurationElement object. (Inherited from ConfigurationElement.) |
![]() | IsModified | Indicates whether this configuration element has been modified since it was last saved or loaded, when implemented in a derived class. (Inherited from ConfigurationElement.) |
![]() | IsReadOnly | Gets a value indicating whether the ConfigurationElement object is read-only. (Inherited from ConfigurationElement.) |
![]() | Reset | Resets the internal state of the ConfigurationElement object, including the locks and the properties collections. (Inherited from ConfigurationElement.) |
![]() | ResetModified | Resets the value of the IsModified method to false when implemented in a derived class. (Inherited from ConfigurationElement.) |
![]() | SerializeElement | Writes the contents of this configuration element to the configuration file when implemented in a derived class. (Inherited from ConfigurationElement.) |
![]() | SerializeToXmlElement | Writes the outer tags of this configuration element to the configuration file when implemented in a derived class. (Inherited from ConfigurationElement.) |
![]() | SetReadOnly | Sets the IsReadOnly property for the ConfigurationElement object and all subelements. (Inherited from ConfigurationElement.) |
![]() | ToString | Returns a string representation of the object. (Overrides Object.ToString.) |
![]() | Unmerge | Modifies the ConfigurationElement object to remove all values that should not be saved. (Inherited from ConfigurationElement.) |
A ConnectionStringSettings object represents a single entry in the connectionStrings configuration file section.
