Registers a mapping from a CLR method to a server-side function.

Namespace:  Mindscape.LightSpeed.Linq
Assembly:  Mindscape.LightSpeed.Linq (in Mindscape.LightSpeed.Linq.dll)
Version: 4.0.0.0 (4.0.0.0)

Syntax

C#
public static void Register(
	MethodInfo clrMethod,
	string sqlFunctionName,
	int implicitArgumentIndex
)
Visual Basic (Declaration)
Public Shared Sub Register ( _
	clrMethod As MethodInfo, _
	sqlFunctionName As String, _
	implicitArgumentIndex As Integer _
)

Parameters

clrMethod
Type: System.Reflection..::.MethodInfo
The CLR method to be mapped.
sqlFunctionName
Type: System..::.String
The server-side function name.
implicitArgumentIndex
Type: System..::.Int32
The position in the server-side function's argument list at which the client-side implicit ('this') argument appears.

Remarks

To illustrate the use of implicitArgumentIndex, consider the following client-side query: from m in uow.Members select m.UserName.IndexOf('a'). On SQL Server this translates to CHARINDEX('a', UserName): i.e. the object to which IndexOf was applied appears at index 1 in CHARINDEX's argument list. So the implicitArgumentIndex should be 1.
