wish to add the ability to ignore a copy of a property when it has a specific value. For example, null, empty string, empty collection

[WuQuDeRen]

mapster has provided the function of not copying the property when the value of the property is null. Can we extend this function to stop copying the property when the value of the property is a series of specific values? It is better to provide a general method (I am not sure which property and which type, but I am sure that the value cannot be these)? Determine whether a property field can be copied before it is copied

  // Can you provide such a method     
  //      Another framework, automapper, already provides similar functionality
  // I don't care about the attribute name, but I care about the attribute value, and providing the attribute name is best when determining the attribute value
  IgnoreMember((srcMember, destMember, srcValue, destValue) =>
  {
      if (srcValue is string srcValueTxt)
      {
          return string.IsNullOrWhiteSpace(srcValueTxt);
      }

      if (srcValue == destValue)
      {
          return true;
      }

      return false;
  })

Hello @WuQuDeRen. Maybe you need Ignore conditionally or Map with condition .

Hello @WuQuDeRen. Maybe you need Ignore conditionally or Map with condition .

You're right, but when there are many attributes, configuring them one by one can be cumbersome. I need a universal and concise way。Similar to the IgnoreNullValues method, but I need to independently determine which values cannot be copied, such as empty strings
