您的第一级通用验证接口，可以灵活地提供结果类型和要验证的模型：
public interface IValidate<T, R>
where T : class
where R : class // where T is any custom result and R is your custom model
{
T Validate(R model);
}
假设，我需要验证将由不同的 sp 完全处理的公司政策：
public interface IValidateCompanyPolicies : IValidate<ValidationResult1, Company>
{
ValidationResult1 Validate(Company model);
}
同样，我还需要检查公司的货币账户、税收、审计等：
public interface IValidateCompanyAccounts : IValidate<ValidationResult2, Company>
{
ValidationResult2 Validate(Company model);
bool HasAuditPassed(Company model);
}
分别。处理两种 IValidate 接口的类
public class ValidateCompanyPolicies : IValidateCompanyPolicies
{
ValidationResult1 Validate(Company model)
{
// Hit stored procedure corresponding to company policies validation
}
}
public class ValidateCompanyAccounts : IValidateCompanyAccounts
{
ValidationResult2 Validate(Company model)
{
// Hit stored procedure corresponding to company's monetary accounts validation
}
bool HasAuditPassed(Company model)
{
// Hit stored procedure corresponding to get company audit results
}
}
我的最终类需要在执行验证后执行所有业务密集型操作：
public class XYZCompany
{
private IValidateCompanyPolicies companyPoliciesValidation;
private IValidateCompanyAccounts companyAccountsValidation;
public XYZCompany(
IValidateCompanyPolicies companyPoliciesValidation,
IValidateCompanyAccounts companyAccountsValidation)
{
// Perform DI
}
public bool UpdateCompany(Company model)
{
var checkPolicies = this.companyPoliciesValidation.Validate(model);
if (checkPolicies.Success)
{
var checkAccounts = this.companyAccountsValidation.Validate(model);
var auditSuccess = this.companyAccountsValidation.HasAuditPassed(model);
if (checkAccounts.Success && auditSuccess)
{
// Perform DB save
}
}
}
}
