private void DapperTransaction()
{
using (IDbConnection con = OpenConnection())
{
IDbTransaction tran = con.BeginTransaction();
try
{
string query = "update T_Role set RoleName='开发主管' where RoleId=4";//更新一条记录
con.Execute(query, null, tran, null, null);
//throw new Exception();
query = "delete from T_Role where RoleId=8";//删除一条记录
con.Execute(query, null, tran, null, null);
tran.Commit();
}
catch (Exception ex)
{
tran.Rollback();
