Parameters

• expression
  Type: Microsoft.Data.Edm.Expressions.IEdmExpression
  Expression to evaluate.

• context
  Type: Microsoft.Data.Edm.Values.IEdmStructuredValue
  Value to use as context in evaluating the expression. Cannot be null if the expression contains paths.

• targetType
  Type: Microsoft.Data.Edm.IEdmTypeReference
  Type to which the result value is expected to conform.

Return Value

Type: Microsoft.Data.Edm.Values.IEdmValue
The value that results from evaluating the expression in the context of the supplied value, asserted to be of the target type.
