LongValidator 类

定义

Int64 值进行验证。Provides validation of an Int64 value.

public ref class LongValidator : System::Configuration::ConfigurationValidatorBase
public class LongValidator : System.Configuration.ConfigurationValidatorBase
type LongValidator = class
    inherit ConfigurationValidatorBase
Public Class LongValidator
Inherits ConfigurationValidatorBase
继承

示例

下面的代码示例演示如何使用 LongValidator 类型。The following code example demonstrates how to use the LongValidator type.

using System;
using System.Configuration;

namespace Microsoft.Samples.AspNet.Validators
{
  class UsingLongValidator
  {
    static void Main(string[] args)
    {
      // Display title.
      Console.WriteLine("ASP.NET Validators");
      Console.WriteLine();

      // Create Long and Validator.
      Int64 testLong =    17592186044416;
      Int64 minLongVal =  1099511627776;
      Int64 maxLongVal =  281474976710656;
      LongValidator myLongValidator = 
       new LongValidator(minLongVal, maxLongVal, false);

      // Determine if the object to validate can be validated.
      Console.WriteLine("CanValidate: {0}",
        myLongValidator.CanValidate(testLong.GetType()));

      try
      {
        // Attempt validation.
        myLongValidator.Validate(testLong);
        Console.WriteLine("Validated.");
      }
      catch (ArgumentException e)
      {
        // Validation failed.
        Console.WriteLine("Error: {0}", e.Message.ToString());
      }

      // Display and wait
      Console.ReadLine();
    }
  }
}
Imports System.Configuration

Namespace Microsoft.Samples.AspNet.Validators
  Class UsingLongValidator
    Public Shared Sub Main()

      ' Display title.
      Console.WriteLine("ASP.NET Validators")
      Console.WriteLine()

      ' Create Long and Validator.
      Dim testLong As Int64 = 17592186044416
      Dim minLongVal As Int64 = 1099511627776
      Dim maxLongVal As Int64 = 281474976710656
      Dim myLongValidator As LongValidator = _
       New LongValidator(minLongVal, maxLongVal, False)

      ' Determine if the object to validate can be validated.
      Console.WriteLine("CanValidate: {0}", _
        myLongValidator.CanValidate(testLong.GetType()))

      Try
        ' Attempt validation.
        myLongValidator.Validate(testLong)
        Console.WriteLine("Validated.")

      Catch e As Exception
        ' Validation failed.
        Console.WriteLine("Error: {0}", e.Message.ToString())
      End Try

      ' Display and wait.
      Console.ReadLine()
    End Sub
  End Class
End Namespace

注解

LongValidator用于确保 long (64位有符号整数)满足特定条件。The LongValidator is used to ensure a long (a 64-bit signed integer) meets specific criteria. 在创建类的实例时,将建立用于验证的条件 LongValidatorThe criteria for validation is established when an instance of the LongValidator class is created. LongValidator(Int64, Int64)构造函数确保所 long 验证的值符合最小和最大长度。The LongValidator(Int64, Int64) constructor ensures that the long value that is being validated adheres to both a minimum and a maximum length. LongValidator(Int64, Int64, Boolean)构造函数同时检查最小值和最大 Int64 值,以及验证范围是否为排他。The LongValidator(Int64, Int64, Boolean) constructor checks both the minimum and maximum Int64 values, as well as whether the validation range is exclusive. LongValidator(Int64, Int64, Boolean, Int64)构造函数检查前面的三个参数,并检查该值是否与 Int64 特定的解决值相等。The LongValidator(Int64, Int64, Boolean, Int64) constructor checks the previous three parameters and also checks whether the Int64 value is equal to a specific resolution value.

CanValidate方法确定所验证的对象类型是否与预期的类型匹配。The CanValidate method determines whether the object type being validated matches the expected type. 要验证的对象作为方法的参数进行传递 ValidateThe object being validated is passed as a parameter of the Validate method.
