Pass Booleabn & date to CRM

I am writing a SQLCLR database project, to update CRM from an legacy SQL server. I have had some great help, so far and thank you to everybody.

I am expanding my original procedures but am stuck on trying to pass a Boolean and a date

    public static void CreateNewCustomer(SqlString LicenceNo, SqlString CompanyName, SqlInt32 Software, SqlInt32 SoftwareStatus,
        SqlBoolean HasDD, SqlDateTime DDposted, SqlString DDsortcode, SqlString DDaccountnumber, SqlString DDaccountname,
        SqlBoolean authorisesubmissions, SqlBoolean payrollclient, SqlBoolean auddisenabled) 
CONNECTION INFO REMOVED
            // Add Licence No
            account.name = LicenceNo.Value;
            // Add Company Name
            account.new_companyname  = CompanyName.Value;
            // Add Software
            account.new_software = new Picklist();
            account.new_software.Value  = Software.Value;
            // Add System Status
            account.new_state = new Picklist();
            account.new_state.Value = SoftwareStatus.Value ;
            // Check Has DirectDebit Mandate
            if  (HasDD = true)
            {
                account.new_ddactive =  true;
                account.new_ddsortcode = DDsortcode.Value;
                account.new_ddaccountnumber = DDaccountnumber.Value;
                account.new_ddaccountname = DDaccountname.Value;
                account.new_ddposted = DDposted.Value;
            }
            else
            {
            }
Error	1	Cannot implicitly convert type 'bool' to 'SqltoCRMTest.crmSdk.CrmBoolean'
Error	2	Cannot implicitly convert type 'System.DateTime' to 'SqltoCRMTest.crmSdk.CrmDateTime'
