Blazor通过内置的组件验证来处理表单验证。但是，如果使用的组件不是内置的，则需要手动为其添加验证。可以通过以下步骤实现：

1. 创建一个非内置组件（例如MyInput），继承Blazor自带的InputBase组件，并重写Validate方法。

public class MyInput : InputBase
{
    protected override bool TryParseValueFromString(string value, out TValue result, out string validationErrorMessage)
    {
        if (typeof(TValue) == typeof(string))
        {
            result = (TValue)(object)value;
            validationErrorMessage = null;
            return true;
        }

        if (typeof(TValue) == typeof(bool))
        {
            if (bool.TryParse(value, out var parsed))
            {
                result = (TValue)(object)parsed;
                validationErrorMessage = null;
                return true;
            }
        }

        // Add more types as necessary

        result = default;
        validationErrorMessage = $"{FieldIdentifier.FieldName} field is not a valid {typeof(TValue).Name}.";
        return false;
    }

    protected override void OnInitialized()
    {
        // Add other initialization as necessary
        base.OnInitialized();
    }

    public override async Task SetParametersAsync(ParameterView parameters)
    {
        await base.SetParametersAsync(parameters);
    }

    public override async Task FocusAsync()
    {
        await base.FocusAsync();
    }

    private IList> _validationFunctions = new List>();
    public void AddValidation(Func validationFunction)
    {
        _validationFunctions.Add(validationFunction);
    }

    public override string GetValidationMessage() =>
        _validationFunctions.Select(f => f()).FirstOrDefault(message => !string.IsNullOrEmpty(message)) ?? base.GetValidationMessage();

    protected override void BuildRenderTree(RenderTreeBuilder builder)
    {
        base.BuildRenderTree(builder);
    }
}

2. 在组件中添加需要的验证逻辑，并将其添加到_validationFunctions列表中。

public class MyFormExample : ComponentBase
{
    private string _name;
    private string _email;
    private string _password;
    private string _confirmPassword;

    private MyInput _
