c#如何在与string.Format类似的VS2017集成开发环境中验证参数

using System;
using System.ComponentModel.DataAnnotations;

public class MyData
{
    [Required(ErrorMessage = "参数不能为空")]
    public string Param1 { get; set; }

    [StringLength(10, ErrorMessage = "参数长度不能超过10个字符")]
    public string Param2 { get; set; }
}

public class ValidationAttribute : Attribute, IValidateObject
{
    public ValidationResult Validate(object value, ValidationContext validationContext)
    {
        var results = new System.Collections.Generic.List<ValidationResult>();
        Validator.TryValidateObject(value, validationContext, results, true);
        
        if (results.Count > 0)
        {
            var validationErrors = string.Join(", ", results.Select(r => r.ErrorMessage));
            throw new ArgumentException(validationErrors);
        }
        
        return ValidationResult.Success;
    }
}

// 在使用的地方调用验证方法
public void DoSomething(MyData data)
{
    var validationAttribute = new ValidationAttribute();
    validationAttribute.Validate(data, new ValidationContext(data));
    
    // 在这里可以继续处理逻辑，因为参数已经通过验证
}
