如何解决窗口服务问题

问题描述

我有一个运行Scheduler的Windows服务来发送电子邮件。

如果我调试Window Service，它可以正常工作并按预期方式发送电子邮件，但安装后它将无法正常工作，并且日志文件中有错误。

已编辑 我已附加App.Config文件以更好地了解

Log4net文件：

解决方法

config部分必须是第一个元素，因为它只是添加了可能不是本机配置的其他配置（来自machine.config）。因此，正如我们所看到的，您只是添加了use Text::CSV_XS; use autodie; open my $out,q{>},q{myFile}; # All of these input strings are parsed correctly,unlike when using "split": # my $run_test = q{sydney,delhi,NY,Russia}; # my $run_test = q{sydney,Russia,"field,with,commas"}; my $run_test = q{sydney,commas",missing,quote}; # binary => 1 : enable parsing binary characters in quoted fields. # auto_diag => 1 : print the internal error code and the associated error message to STDERR. my $csv = Text::CSV_XS->new( { binary => 1,auto_diag => 1 } ); if ( $csv->parse( $run_test ) ) { print {$out} map { "$_\n" } $csv->fields; } else { print STDERR q{parse() failed on: },$csv->error_input,qq{\n}; } 和Entity Framework组件的部分。出于配置目的，它必须是根目录的第一个子标记。错误消息已经表明：

每个配置文件只允许一个元素，如果 present必须是根元素的第一个子元素。

将log4net移至App.config的顶部：

configSections

提示：使用EventViewer记录Windows服务，这很有帮助。
