Hi,
I have declared a SqlParameter Araay (SqlParameter[] paramFields = new SqlParameter[100]). And i am initializing the Arraay as below.

C#

SqlParameter[] getFormId = 
{ new SqlParameter("@fid1", SqlDbType.VarChar, 50) { Value = fID1 }
new SqlParameter("@fid2", SqlDbType.VarChar, 50) { Value = fID2 }
new SqlParameter("@fid3", SqlDbType.VarChar, 50) { Value = fID3 }
new SqlParameter("@fid4", SqlDbType.VarChar, 50) { Value = fID4 } };

I want to clear the array getFormId for reuse.
How can i clear it.?

Solution 1

C#

getFormId = null;

- or -

C#

getFormId = new SqlParameter[100];

While I commend you for parametrizing your SQL, I strongly urge to take a closer look at what you are doing. A query with 100 parameters is a huge red flag and screams refactor to a better solution.

Solution 3

This is pretty much trivial using Array.Clear

C#

Array.Clear(getFormId,0,getFormId.Length);

You can use that method to truncate or completely empty an array, documentation can be found at:
