Question

Here is the code:

internal static void UpdateErrorLogTable(string type, string location, string method, Exception _error, string ftpDirectory, string remoteName, string localName)
    {
        try
        {
            using (SqlConnection databaseConnection = GetDatabaseConnection())
            {
                using (SqlCommand cmd = GetSqlCommand("ins_error_log", databaseConnection))
                {
                    SqlParameter log_date = cmd.Parameters.Add("@log_date", SqlDbType.DateTime);
                    SqlParameter exception_type = cmd.Parameters.Add("@exception_type", SqlDbType.VarChar);
                    SqlParameter class_name = cmd.Parameters.Add("@class_name", SqlDbType.VarChar);
                    SqlParameter method_name = cmd.Parameters.Add("@method_name", SqlDbType.VarChar);
                    SqlParameter error_msg = cmd.Parameters.Add("@error_msg", SqlDbType.VarChar);
                    SqlParameter stack_trace_msg = cmd.Parameters.Add("@stack_trace_msg", SqlDbType.VarChar);
                    SqlParameter target_site_msg = cmd.Parameters.Add("@target_site_msg", SqlDbType.VarChar);
                    SqlParameter ftp_directory = cmd.Parameters.Add("@ftp_directory", SqlDbType.VarChar);
                    SqlParameter ftp_name = cmd.Parameters.Add("@ftp_name", SqlDbType.VarChar);
                    SqlParameter ftp_path = cmd.Parameters.Add("@ftp_path", SqlDbType.VarChar);
                    SqlParameter inner_exception_msg = cmd.Parameters.Add("@inner_exception_msg", SqlDbType.VarChar);

                    log_date.Value = m_todaysDate;
                    exception_type.Value = type;
                    class_name.Value = location;
                    method_name.Value = method;
                    error_msg.Value = _error.Message;
                    stack_trace_msg.Value = _error.StackTrace;
                    target_site_msg.Value = _error.TargetSite;
                    ftp_directory.Value = ftp_directory;
                    ftp_name.Value = remoteName;
                    ftp_path.Value = localName;
                    inner_exception_msg.Value = _error.InnerException;

                    cmd.ExecuteNonQuery();
                }
            }  // using databaseConnection
        } //end of TRY statement
        catch (SqlException e)
        {
            logFile.SendToLog("SqlException", "Logs\\LogsDataAccess.cs", "UpdateErrorLogTable()", e);
        } //end of SqlException CATCH statement
    } //end of method UpdateErrorLogTable

The error I get is an InvalidCastException but it happens when attempting to execute

cmd.ExecuteNonQuery();

The part I can’t figure out is why am I getting an InvalidCastException here and not at one of the points above where I’m assigning values. I stepped through the code in Debug line-by-line of this and it only gets the error when attempting to execute the code at that one line.

I performed a Google search for

Failed to convert parameter value from a RuntimeMethodInfo to a String

but no hits. So I searched for

convert from RuntimeMethodInfo to String

and still no luck.

To help you understand the code a little better, the statement

GetSqlCommand("ins_error_log", databaseConnection)

basically goes out and recognizes the info in quotes is a Stored Procedure and not a query string.

All this code above has been used throughout the application (written by someone else) and all I did was copy it and make the necessary modifications to the stored procedure name, the SQL parameters, and the values inserted.

I appreciate all your help!

*Note: I tried setting the TAG for this question as “RuntimeMethodInfo” but it wouldn’t let me because I have less than a 1500 reputation. Maybe someone else can do it for me or give me the permissions to handle this.

Answer 1

It’s this line:

target_site_msg.Value = _error.TargetSite;

Exception.TargetSite is a MethodBase, not a string. Try changing to:

target_site_msg.Value = _error.TargetSite.Name;
