Question: How we hand sql exceptions? What is the class that handles SqlServer exceptions?

Answer: SqlExceptionclass is created whenever the .NET Framework Data Provider for SQL Server encounters an error generated from the server. (Client side errors are thrown as standard common language runtime exceptions.) SqlException always contains at least one instance of SqlError.

...

try
{
myCommand.Connection.Open();
}
catch (SqlException e)
{
string errorMessages = "";

for (int i=0; i < e.Errors.Count; i++)
{
errorMessages += "Index #" + i + " " +
"Message: " + e.Errors[i].Message + " " +
"LineNumber: " + e.Errors[i].LineNumber + " " +
"Source: " + e.Errors[i].Source + " " +
"Procedure: " + e.Errors[i].Procedure + " ";
}

System.Diagnostics.EventLog log = new System.Diagnostics.EventLog();
