SqlParameter dynamic splicing of multiple parameters to solve the problem of parameterization

Multiple parameterization is relatively easy to fix, and multiple dynamic ones are a little bit. . . Sort out the problems encountered at work and share them with the code

            SqlParameter[] param = new SqlParameter[] { };
            List<SqlParameter> sqlParameterList = new List<SqlParameter>(); //Here is the key point, you need to remember it.

            if (!string.IsNullOrEmpty(cpId))
            {
                sql += " and  a.cpId =@cpId";
                sqlParameterList.Add(new SqlParameter { ParameterName = "@cpId", Value = cpId, SqlDbType = SqlDbType.VarChar, Size = 20 });
            }

            if (!string.IsNullOrEmpty(cpName))
            {
                sql += " and  b.name like @cpName";
                sqlParameterList.Add(new SqlParameter { ParameterName = "@cpName", Value = '%' + cpName + '%', SqlDbType = SqlDbType.VarChar, Size = 20 });

            }

            if (!string.IsNullOrEmpty(status))
            {
                sql += " and  b.status = @status";
                sqlParameterList.Add(new SqlParameter { ParameterName = "@status", Value = status, SqlDbType = SqlDbType.Int, Size = 10 });

            }

            //sql += " order by createdatetime desc ";

            param = sqlParameterList.ToArray();

In the end, it is ok to use param
