How to give validation for password in mvc

Seshu B

password to be 8 characters long with at least 1 special character, 1 numeral and mix of letters

what I have tried :-

[Required(ErrorMessage = "Please enter the Password")]
[DataType(DataType.Password)]
[StringLength(8, ErrorMessage = "The Password must be at least 5 - 8 characters long.", MinimumLength = 5)]
[Display(Name = "Password")]
public string Password { get; set; }

You need to use Regular expression to validate the same. Find below:
[Required]
[StringLength(18, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)]
[RegularExpression(@^((?=.*[a-z])(?=.*[A-Z])(?=.*\d)).+$)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
