Apparently, you can.

This link talks about calling your .NET assembly directly:
Execute .NET Code under SQL Server 2005[^]

While this link talks about generating a COM wrapper and calling the COM wrapper:

You need to add the dll as an assembly in the database.

SQL

--=============================================================
-- Create Assembly Template
--=============================================================
IF EXISTS(
    SELECT *
      FROM sys.assemblies
     WHERE name = N'<assembly_name, SYSNAME, MyClass>'
)
DROP ASSEMBLY <assembly_name, SYSNAME, MyClass>;
GO

CREATE ASSEMBLY <assembly_name, SYSNAME, MyClass>
FROM N'<Assembly_DLL_Name, nvarchar(4000), Path_MyAssembly.dll>'
WITH PERMISSION_SET = <Safe_External_Access_Unsafe, , SAFE>;
GO

No.
You cannot call .NET functions from within SQL server, only the other way around.
