设置EmailSettingNames.Smtp.EnableSsl导致“字符串未被识别为有效的布尔值”错误

Question

我已经设置了aspnet样板来发送电子邮件。我使用以下命令设置了默认值：

    public class AppSettingProvider : SettingProvider
{
    public override IEnumerable<SettingDefinition> GetSettingDefinitions(SettingDefinitionProviderContext context)
    {
        return new[]
        {
            new SettingDefinition(EmailSettingNames.DefaultFromAddress, "", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.DefaultFromDisplayName, "", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Host, "127.0.0.1", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Port, "25", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.UserName, XXXXX, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Password, XXXXX, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Domain, string.Empty, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.EnableSsl, "true", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.UseDefaultCredentials, string.Empty, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true)
        };
    }
}

但是，当我发送电子邮件时，它会生成“字符串未被识别为有效的布尔值”异常，我还应如何定义EmailSettingNames.Smtp.EnableSsl属性，以使其正确应用？

下面是正确的一个：

public class AppSettingProvider : SettingProvider
{
    public override IEnumerable<SettingDefinition> GetSettingDefinitions(SettingDefinitionProviderContext context)
    {
        return new[]
        {
            new SettingDefinition(EmailSettingNames.DefaultFromAddress, "", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.DefaultFromDisplayName, "", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Host, "127.0.0.1", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Port, "25", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.UserName, XXXXX, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Password, XXXXX, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.Domain, string.Empty, scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.EnableSsl, "true", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true),
            new SettingDefinition(EmailSettingNames.Smtp.UseDefaultCredentials, "false", scopes: SettingScopes.Application | SettingScopes.Tenant | SettingScopes.User, isVisibleToClients: true, isInherited: true)
        };
    }
}
更正：UseDefaultCredentials不能为空字符串。
