C#验证:没有硬编码的属性名字符串的IDataErrorInfo？

public class MyData : IDataErrorInfo
{
    public string Name { get; set; }
    public int Age { get; set; }

    public string this[string columnName]
    {
        get
        {
            return GetValidationError(columnName);
        }
    }

    public string Error { get { return null; } }

    private string GetValidationError(string propertyName)
    {
        string error = null;

        switch (propertyName)
        {
            case nameof(Name):
                if (string.IsNullOrEmpty(Name))
                    error = "Name不能为空";
                break;

            case nameof(Age):
                if (Age < 0 || Age > 100)
                    error = "Age必须在0到100之间";
                break;
        }

        return error;
    }
}

MyData data = new MyData();
data.Name = "John";
data.Age = 150;

string nameError = data[nameof(MyData.Name)]; // 获取Name属性的错误信息
string ageError = data[nameof(MyData.Age)]; // 获取Age属性的错误信息
