C# 如何修复无效URI：asp.net核心问题中无法确定URI的格式

我在我的Asp.net核心程序中使用serilog和Seq，但我不断得到上述错误。我的Seq服务器正在运行。分别在

appsetting.json

和

startup.cs

中找到下面的配置

Appsetting.json

StartUp.cs

对于

loggingBuilder.AddSeq（“Seq”）

，您需要传递url而不是

Seq

    //
// Summary:
//     Extends Microsoft.Extensions.Logging.ILoggerFactory with methods for configuring
//     Seq logging.
public static class SeqLoggerExtensions
{
    //
    // Summary:
    //     Adds a Seq logger configured from the supplied configuration section.
    //
    // Parameters:

    //
    //   configuration:
    //     A configuration section with details of the Seq server connection.

    public static ILoggerFactory AddSeq(this ILoggerFactory loggerFactory, IConfigurationSection configuration);
    //
    // Summary:
    //     Adds a Seq logger.
    //
    // Parameters:
    //   loggerFactory:
    //     The logger factory.
    //
    //   serverUrl:
    //     The Seq server URL; the default is http://localhost:5341.
    //
    //   apiKey:
    //     A Seq API key to authenticate or tag messages from the logger.
    //
    //   minimumLevel:
    //     The level below which events will be suppressed (the default is Microsoft.Extensions.Logging.LogLevel.Information).
    //
    //   levelOverrides:
    //     A dictionary mapping logger name prefixes to minimum logging levels.
    //
    // Returns:
    //     A logger factory to allow further configuration.
    public static ILoggerFactory AddSeq(this ILoggerFactory loggerFactory, string serverUrl = "http://localhost:5341", string apiKey = null, LogLevel minimumLevel = LogLevel.Information, IDictionary<string, LogLevel> levelOverrides = null);
    //
    // Summary:
    //     Adds a Seq logger.
    //
    // Parameters:
    //   loggingBuilder:
    //     The logging builder.
    //
    //   serverUrl:
    //     The Seq server URL; the default is http://localhost:5341.
    //
    //   apiKey:
    //     A Seq API key to authenticate or tag messages from the logger.
    //
    // Returns:
    //     A logging builder to allow further configuration.
    public static ILoggingBuilder AddSeq(this ILoggingBuilder loggingBuilder, string serverUrl = "http://localhost:5341", string apiKey = null);
    //
    // Summary:
    //     Adds a Seq logger configured from the supplied configuration section.
    //
    // Parameters:
    //   loggingBuilder:
    //     The logging builder.
    //
    //   configuration:
    //     A configuration section with details of the Seq server connection.
    //
    // Returns:
    //     A logging builder to allow further configuration.
    public static ILoggingBuilder AddSeq(this ILoggingBuilder loggingBuilder, IConfigurationSection configuration);
}

并使用like

loggingBuilder.AddSeq（Configuration.GetSection（“Seq”））

如果需要组合
serilog
和
Seq
，请参阅

显示您可能应该执行的操作，而不是将
“Seq”
作为参数传递。通过将
Seq
传递到
loggingBuilder.AddSeq（“Seq”）来实现什么？
 services.AddLogging(loggingBuilder =>
 {
     loggingBuilder.AddSeq("Seq");
 });
