Script With If Condition For Multiple Input Parameter That Can Be NULL

I want to write an Query for a report that has 7 parameters. I want to allow Null for these parameters but at the same time in the Query i want to put an AND condition for all the parameters. I cannot put an OR condition.

For Example;
If i have a report with 2 parameters then the script will have 2* 2 If conditions

something like:-

if( @parameter1 is not Null and @parameter is not Null)
select A, B, C
From Table 1
Where parameter1 = @parameter1 and parameter2 = @prameter2

if( @parameter1 is not Null AND @parameter2 is Null)



select A, B, C
From Table 1
Where parameter1 = @parameter1

If( @parameter1 is Null AND @parameter2 is Not Null)
select A, B, C
From Table 1
Where parameter2 = @parameter2

If( @parameter1 is Null AND @parameter2 is Null)
select A, B, C
From Table 1


For 7 parameter there will be way too many If conditions. Is there an better approch to write a Query for such a situation?
