[wix-users] how to pass multiple arguments to C# custom action

[Brian Enderle]

I don't know for sure, but my guess is your collection does not have any
items in it.  Can you add a log statement and get the number of elements in
'values' (i.e., 'values.Count()').


Here is an example of setting up parameters in WiX and then using them in
the CustomAction by parameter name:

SQLSERVER, SQLUSER, SQLPASSWORD, and INSTALL_SCRIPTS_FOLDER are variables
captured by installation setup screen.


<Fragment>

    <!-- Setup SQL User credentials -->
    <util:User Id="SQLUser" Name="[SQLUSER]" Password="[SQLPASSWORD]" />

    <!-- Need to perform a CustomAction to execute SQL command script with
parameters -->
    <CustomAction Id="ExecuteSQLParameters"
                  Return="check"
                  Property="ExecuteSQL"

Value="Server=[SQLSERVER];Database=master;Username=[SQLUSER];Password=[SQLPASSWORD];Directory=[INSTALL_SCRIPTS_FOLDER]"
/>

    <CustomAction Id="ExecuteSQL"
                  BinaryKey="CustomAction.CA"
                  DllEntry="ExecuteSQLCustomAction"
                  Execute="deferred"
                  Impersonate="no"
                  Return="check" />

</Fragment>




CustomAction method:


        [CustomAction]
        public static ActionResult ExecuteSQLCustomAction(Session session)
        {
            // Get SQL credentials
           Models.Database _dbInfo = new Models.Database();
            _dbInfo.ServerName = session.CustomActionData["Server"];
            _dbInfo.DatabaseName = session.CustomActionData["Database"];
            _dbInfo.Username = session.CustomActionData["Username"];
            _dbInfo.Password = session.CustomActionData["Password"];
            _dbInfo.IntegratedSecurity = false;
            session.Log(String.Format("*** _dbInfo: {0}, {1}",
_dbInfo.ServerName, _dbInfo.Username));
        }

If you can't explain it simply, you don't understand it well enough.  -
