Public Function Invoke (function As EdmFunction, ParamArray arguments As DbExpression()) As DbFunctionExpressionParameters
- function
- EdmFunction
Metadata for the function to invoke.
- arguments
- DbExpression[]
Expressions that provide the arguments to the function.
Returns
A new DbFunctionExpression representing the function invocation.
Exceptions
function is null, or arguments is null or contains null.
The count of arguments does not equal the number of parameters declared by function, or arguments contains an expression that has a result type that is not equal or promotable to the corresponding function parameter type.
