Hi RamPrasad,

Here is code from msdn article https://msdn.microsoft.com/en-us/library/aa629483.aspx

switch (myEnum) { case ABC::A: ... break; case ABC::B: ... break; case ABC::C: ... break; default: ... break; }

Hi Ram Prasad,

This Code is used to import data from CSV you can put your enum value in switch().

switch (str2enum(campaignStatus,strLRTrim((conPeek(readcon,3)))))

{

case smmCampaignStatus::Planning:

campaignTable.CampaignStatus = smmCampaignStatus::Planning;

break;

case smmCampaignStatus::FollowUp:

campaignTable.CampaignStatus = smmCampaignStatus::FollowUp;

break;

case smmCampaignStatus::Cancelled:

campaignTable.CampaignStatus = smmCampaignStatus::Cancelled;

break;

case smmCampaignStatus::Closed:

campaignTable.CampaignStatus = smmCampaignStatus::Closed;

break;

case smmCampaignStatus::InProcess:

campaignTable.CampaignStatus = smmCampaignStatus::InProcess;

break;

case smmCampaignStatus::Response:

campaignTable.CampaignStatus = smmCampaignStatus::Response;

break;

}

Hi Ram Prasad,

You can check this peace of code that might be help

DictEnum dictEnum = new DictEnum(enumId);

int numEnum;

;

// Test 1: we have a variable of desired Enum type (salesPurchIn of type SalesPurch), we can use the str2enum function

numEnum = 0;

while(numEnum < dictEnum.values())

{

if(label == dictEnum.index2Label(numEnum))

{

info(int2str(dictEnum.index2value(numEnum)));

break;

}

numEnum++;

}

// Test 2: we don't have any variable, but we know the EnumId

salesPurchOut = str2enum(salesPurchIn, label);

info(int2str(salesPurchOut));

// Test 3: we can do it with name2label anyway...

RamPrasad: It's true that enums are actually integers under the hood, but is using numbers instead of enums really better? Using numeric constant used to be the practice in older programming languages, before enums were invented to make code easier to write, verify at compile time, make it more readable and so on.

That there is another solution doesn't always mean that it makes sense to use it.
