错误： System.OverflowException：对于Int32，值太大或太小。在System.Number.ParseInt32（String s，NumberStyles样式，NumberFormatInfo信息）处于System.Convert.ToInt32（String value）的Pages_register.Button3_Click（Object sender，EventArgs e）中的c：\ Users \ shreya \ Documents \ Visual Studio 2015 \ Project_Greetings \ Pages \ register.aspx.cs：第38行我的模型类

public partial class UserInformation1
{
public int Id { get; set; }
public string GUID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Address { get; set; }
public Int32 PostalCode { get; set; }
public Int32 PhoneNo { get; set; }
public string Email { get; set; }
}

此错误的任何解决方案

Answer 1

使用string类型存储电话号码和邮政编码

但要避免此异常，您可以使用int.TryParse()：

int result;
if(!int.TryParse(txtPostalCode.Text, out result))
{
    // process wrong input
}
