Provides a command tree API.
Classes
| DbExpressionBuilder |
Provides an API to construct DbExpressions and allows that API to be accessed as extension methods on the expression type itself. |
| EdmFunctions |
Provides an API to construct DbExpression s that invoke canonical EDM functions, and allows that API to be accessed as extension methods on the expression type itself. |
| Row |
Provides a constructor-like means of calling NewRow(IEnumerable<KeyValuePair<String,DbExpression>>). |
Remarks
The System.Data.Common.CommandTrees.ExpressionBuilder API is used to create expressions, which are represented by DbExpression objects. The command tree API provided by the DbExpressionBuilder class has the following characteristics:
Functional: DbExpression objects are constructed using functional patterns that provide a natural flow of construction.
Loosely-coupled: A DbExpression object is not bound to any specific command tree and can be used in any context where type agreement is satisfied.
Immutable: The API consists entirely of immutable types; mutability may be simulated by substituting new values while rebuilding an expression tree.
