c# - Application closes without a reason -

my applications quit no reason without error, stops, , don't see why happens. whenever go through in debug mode, stops on line database.cmd.executenonquery()

database.con.open(); using(database.cmd = new idb2command(query, database.con)) {    database.cmd.commandtext = query;     foreach(var value in para)    {       database.cmd.parameters.addwithvalue(value.key, value.value);    }     database.cmd.executenonquery(); } database.con.close(); 

my query wasn't correct, rather thought connection, searched in wrong place... anyways, guys :-)

put whole code try catch block , print exception message in label or popup. exact error being thrown. while in debug mode, can see details of error on exception e part.

try {     //your code } catch(exception e) {     label1.text = e.message; } 

the issue may database instance.
