SQLBulkCopy with FireTrigger Error

Question

Hi guys. Kindly help fix this issue.

I get the following error while trying to fire sql trigger from asp.net webpage

Format of the initialization string does not conform to specification starting at index 0.

My code is as below: The error is on the last line.

SqlConnection con = new

SqlConnection(ConfigurationManager.ConnectionStrings["warehousedbCon"].ToString());

DataTable dtDispac = (DataTable)ViewState["Dispatches"];

connection();

//creating object of SqlBulkCopy

using (SqlBulkCopy objbulk = new SqlBulkCopy("con", SqlBulkCopyOptions.FireTriggers))
