如何命名使用VB.net创建的Excel工作簿下面是我的代码

public class CustomerBuilder {

    private Customer customer = new Customer();

    public CustomerBuilder setName(String name){
        customer.setName(name);
        return this;
    }

    public CustomerBuilder setSurname(String surname){
        customer.setSurname(surname);
        return this;
    }

    public CustomerBuilder setAge(int age){
        customer.setAge(age);
        return this;
    }

    public CustomerBuilder setEmail(String email){
        customer.setEmail(email);
        return this;
    }

    public Customer build()  {

        return customer;
    }

}
public class OrderBuilder {
   private Order order = new Order();

   public OrderBuilder setCustomer(Customer customer){
       order.setCustomer(customer);
       return this;
   }

   public OrderBuilder setProduct(Product product){
       order.setProduct(product);
       return this;
   }

   public OrderBuilder setQuantity(int quantity){
       order.setQuantity(quantity);
       return this;
   }

   public OrderBuilder setOrderDate(LocalDate orderDate){
       order.setOrderDate(orderDate);
       return this;
   }

   public Order build(){
       return order;
   }

}

public class ProductBuilder {

    private Product product = new Product();

    public ProductBuilder setCategory(Category category){
        product.setCategory(category);
        return this;
    }

    public ProductBuilder setName(String name){
        product.setName(name);
        return this;
    }

    public ProductBuilder setPrice(BigDecimal bigDecimal){
        product.setPrice(bigDecimal);
        return this;
    }

    public Product build() {
        return product;
    }
}

我希望下面的行产生设置工作簿的名称，但它总是给我一个错误。

appXL = CreateObject("Excel.Application")
wbXL = appXL.Workbooks.Add()

我也尝试了下面的代码，但是没有用。

wbXL.Name = "WorkbookName"

任何帮助将不胜感激

感谢@Storax提供指针。我能够想到这个

if (this.RegistrationForm.valid) {
  if (this.RegistrationForm.get('password1') == this.RegistrationForm.get('password2')) {
    this.MyService.Register(this.RegistrationForm.value).subscribe((data) => {}, error => this.errorMessage = error)
  } else {
    this.errorMessage = "cdscs";
  }
}

constructor(private fb: FormBuilder, private MyService: RoadSignService) {
        this.RegistrationForm = this.fb.group({
            Id: 0,
            name: ['', [Validators.required]],
            email: ['', [Validators.required]],
            gender: ['', [Validators.required]],
            department: ['', [Validators.required]],
            address: ['', [Validators.required]],
            password1: ['', [Validators.required]],
            password2: ['', [Validators.required]]
        })
    }

我将编写代码以查看目录并在代码重新运行时随时删除文件，因此它不会要求覆盖，因为它已经存在。

非常感谢你们
