C#构造函数在执行代码后调用构造函数

Question

我看过有关构造函数链的答案，但它们不适用于我的问题。

我有一个需要几个参数的构造函数:

public SerilogHelper(string conString, int minLevel)
    {
        var levelSwitch = new LoggingLevelSwitch();
        levelSwitch.MinimumLevel = (Serilog.Events.LogEventLevel)(Convert.ToInt32(minLevel));

        _logger = new LoggerConfiguration()
            .MinimumLevel.ControlledBy(levelSwitch)
            .WriteTo.MSSqlServer(connectionString: conString, 
                                 tableName: "Logs", 
                                 autoCreateSqlTable: true)
            .CreateLogger();
    }

这个构造函数的一个特定客户端没有参数所需的值，所以我希望能够调用这个简单的构造函数，它将获得所需的值，然后调用第一个构造函数:

public SerilogHelper()
    {
        string minLevel = SSOSettingsFileManager.SSOSettingsFileReader.ReadString(
          "LCC.Common", "serilog.level");
        string conString = SSOSettingsFileManager.SSOSettingsFileReader.ReadString(
          "LCC.Common", "serilog.connectionstring");

        SerilogHelper(conString, minLevel);
    }

问题是，我在调用第二个构造函数时出现红色波浪形消息 SerilogHelper is a 'type' but used like a 'variable'

为什么不直接添加这些参数呢？

// this assumes that SSOSettingsFileManager is static class
// this will automatically call these methods before passing 
// values to another ( non parameterless ) constructor
public SerilogHelper()
    : this ( 
        SSOSettingsFileManager.SSOSettingsFileReader.ReadString(
            "LCC.Common", "serilog.connectionstring"
        ),
        SSOSettingsFileManager.SSOSettingsFileReader.ReadString(
            "LCC.Common", "serilog.level"
        )
    )
{

}

// This will be called from default ( parameterless )
// constructor with values retrieved from methods
// called in previous constructor.
public SerilogHelper(string conString, int minLevel)
{
        var levelSwitch = new LoggingLevelSwitch();
        levelSwitch.MinimumLevel = (Serilog.Events.LogEventLevel)(Convert.ToInt32(minLevel));

        _logger = new LoggerConfiguration()
            .MinimumLevel.ControlledBy(levelSwitch)
            .WriteTo.MSSqlServer(connectionString: conString, 
                                 tableName: "Logs", 
                                 autoCreateSqlTable: true)
            .CreateLogger();
}
