ResourceExpressionBuilder Class
Provides code to the page parser for assigning property values on a control.
System.Web.Compilation::ExpressionBuilder
System.Web.Compilation::ResourceExpressionBuilder
Assembly: System.Web (in System.Web.dll)
The ResourceExpressionBuilder type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | ResourceExpressionBuilder | Initializes a new instance of the ResourceExpressionBuilder class. |
| Name | Description | |
|---|---|---|
![]() | SupportsEvaluate | Returns a value indicating whether an expression can be evaluated in a page that uses the no-compile feature. (Overrides ExpressionBuilder::SupportsEvaluate.) |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | EvaluateExpression | Returns a value from a resource file. (Overrides ExpressionBuilder::EvaluateExpression(Object, BoundPropertyEntry, Object, ExpressionBuilderContext).) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetCodeExpression | Returns a code expression to evaluate during page execution. (Overrides ExpressionBuilder::GetCodeExpression(BoundPropertyEntry, Object, ExpressionBuilderContext).) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() ![]() | ParseExpression(String) | Returns an object that represents the parsed expression. |
![]() | ParseExpression(String, Type, ExpressionBuilderContext) | Returns an object that represents the parsed expression. (Overrides ExpressionBuilder::ParseExpression(String, Type, ExpressionBuilderContext).) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
The ResourceExpressionBuilder class creates code to retrieve resource values when the page is executed. A resource file typically contains information localized for a particular language or culture.
A resource expression takes the form <%$ Resources: ClassKey, ResourceKey %> within the page. The part of the expression before the colon (:) designates the type of expression builder to use, and the part after the colon signifies the class name and resource key. The preceding expression would retrieve the following value from a file named ClassKey.resx:
<data name="ResourceKey"><value xml:space="preserve">Hello!</value></data>
When the page parser encounters an expression with the Resources prefix, it creates an instance of the ResourceExpressionBuilder class. The ResourceExpressionBuilder class either evaluates the expression or generates code to return a value for the expression when the page is executed.
If the expression is encountered in a page that will be compiled, the ResourceExpressionBuilder object generates code that retrieves the specified value from the resource file. If the expression is encountered in a page that will not be compiled, the ResourceExpressionBuilder object returns the value from the resource file when the page is parsed.
