EPPlus的验证方法如何工作？

Question

我使用EPPlus作为计算服务器。这里是我的代码：

​​

我读过的地方，验证（）方法抛出无效数据的异常。它没有。 我的问题：如何使用Validate（）方法？

Answer 1

这将取决于哪些单元格的内容和验证的操作员的设置：

http://epplus.codeplex.com/SourceControl/latest#EPPlus/DataValidation/ExcelDataValidationOperator.cs

/// <summary> 
/// Operator for comparison between Formula and Formula2 in a validation. 
/// </summary> 
public enum ExcelDataValidationOperator 
{ 
    any, 
    equal, 
    notEqual, 
    lessThan, 
    lessThanOrEqual, 
    greaterThan, 
    greaterThanOrEqual, 
    between, 
    notBetween 
} 

的ExcelDataValidationDateTime（最终）从ExcelDataValidationWithFormula<IExcelDataValidationFormulaDateTime>其中包含Validate()的实行得出：

http://epplus.codeplex.com/SourceControl/latest#EPPlus/DataValidation/ExcelDataValidationWithFormula.cs

public override void Validate() 
{ 
    base.Validate(); 
    if (Operator == ExcelDataValidationOperator.between || Operator == ExcelDataValidationOperator.notBetween) 
    { 
     if (string.IsNullOrEmpty(Formula2Internal)) 
     { 
      throw new InvalidOperationException("Validation of " + Address.Address + " failed: Formula2 must be set if operator is 'between' or 'notBetween'"); 
     } 
    } 
} 

因此，这将抛出异常（无效）时，验证操作是要么ExcelDataValidationOperator.between或ExcelDataValidationOperator.notBetween和Forumla2未设置（不与主Formula混淆）。换句话说，当您使用需要比较两个值/公式进行比较但仅设置一个的操作时，它认为验证器无效。
