增加 SQL 命令的命令超时

我有点小问题，希望有人能给我一些建议.我正在运行一个SQL命令，但由于有大量数据，这个命令似乎需要大约2分钟才能返回数据.但是默认连接时间是30秒，我如何增加这个时间，并将其应用到这个命令中？

public static DataTable runtotals(string AssetNumberV, string AssetNumber1V)
{
    DataTable dtGetruntotals;

    try
    {
        dtGetruntotals = new DataTable("Getruntotals");

        //SqlParameter AssetNumber = new SqlParameter("@AssetNumber", SqlDbType.VarChar, 6);
        //AssetNumber.Value = AssetNumberV; 

        SqlParameter AssetNumber = new SqlParameter("@AssetNumber", SqlDbType.VarChar, 10);
        AssetNumber.Value = AssetNumberV;

        SqlParameter AssetNumber1 = new SqlParameter("@AssetNumber1", SqlDbType.VarChar, 10);
        AssetNumber1.Value = AssetNumber1V;

        SqlCommand scGetruntotals = new SqlCommand("EXEC spRunTotals @AssetNumber,@AssetNumber1 ", DataAccess.AssetConnection); 
        // scGetruntotals.Parameters.Add(AssetNumber);
        scGetruntotals.Parameters.Add(AssetNumber);
        scGetruntotals.Parameters.Add(AssetNumber1);

        SqlDataAdapter sdaGetruntotals = new SqlDataAdapter();
        sdaGetruntotals.SelectCommand = scGetruntotals;
        sdaGetruntotals.Fill(dtGetruntotals);

        return dtGetruntotals;
    }
    catch (Exception ex)
    {
        MessageBox.Show("Error Retriving totals Details: Processed with this error:" + ex.Message);
        return null;
    }
}
