you are aleady adding the values in SQLCommand. You dont need to pass any parameter values. Remove the code of adding param and param1. It should work..

Solution 2

SqlCommand cmd = new SqlCommand("select * from progressive where mem_id= @v_mem_id and dist_code=@v_dist_code", con);
cmd.Parameters.AddWithValue("@v_mem_id", v_mem_id);
cmd.Parameters.AddWithValue("@v_dist_code", v_dist_code);

connection.Open() // your SqlConnection
SqlDataReader dr = cmd.ExecuteReader();

while(dr.read())
{
// Your Object filling with data use dr.getValue(columnPosition) or dr["ColumnName"].ToString()
// dr.getString(columnPosition) or dr.getInt(columnPosition) according your data type
}

connection.Close() // close SqlConnection

// thats all, keep your code in try catch :)

C#

SqlCommand cmd = new SqlCommand("select * from progressive where mem_id= '" + v_mem_id + "' and dist_code='" + v_dist_code + "'", con);
            SqlDataReader reader = cmd.ExecuteReader();
            if (reader.HasRows)
            {

            }
            else
            {
            }

And i believe you have some values in v_mem_id and v_dist_code. As i said in comment, you dont need to pass any param as your commandstring contains the values already.
