.net static Datatable method with parameter : I need to bind an asp repeater with a sql query, that includes a parameter but im using a public Static method, so i dont know how to pass a variable to this method :

Code behind aspx webfile :

        protected void Page_Load(object sender, EventArgs e)
        {
            this.DataAdmin();

            
        }

        public void DataAdmin()
        {
            /****Resultado is the repeater name    */
            Datatable dataAdmin = DescargarDocumentos.SolicitarDatosDocumento() ;
            Resultados.DataSource = dataAdmin;
            Resultados.DataBind();
        }

Code behind the class 


    public class DescargaDocumentos
    {
              
        public static DataTable SolicitarDatosDocumentos()
        {
            /* */
            SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["Conexion"].ConnectionString);
            SqlDataReader reader;
            conn.Open();
            SqlCommand vistadocumentos = new SqlCommand("ultimasolicitud", conn);
            vistadocumentos.CommandType = CommandType.StoredProcedure;

             /* i need to add the parameter here */
            vistadocumentos.Parameters.AddWithValue("@numero",numero);/*error is here because i cant get pass this parameter to a static method*/
            reader = vistadocumentos.ExecuteReader();
            DataTable test = null;
            if (reader.HasRows)
            {
                test = new DataTable("test");
                test.Load(reader);
            }
            reader.Close();
            conn.Close();
            return test;
        }
    }


The error is on the variable number because i cant "pass the variable numero" to a static method, is it possible to do it?

btw this is the stored procedure (should return file names according to the order number)

    alter  procedure documentlist (
	           @numero int
    )
    as
    begin
        select 
        tipo_de_documento.tipo_documento,detalle_documentos.nombre_documento 
        from tipo_de_documento inner join has_tipo on 
        tipo_de_documento.numero=has_tipo.numero_tipo inner join 
        detalle_documentos 
        on has_tipo.id_detalle= detalle_documentos.id_detalle inner join 
        Documentos 
        on detalle_documentos.num_documento= documentos.num_documento where 
        documentos.num_solicitud=@numero

    end
