Mapping/Transformation to handle Enum model with LinqToExcel

Question

I'm having an issue handling one column of the Excel file I'm trying to import to my database. The property refers to an Enum model. I tried putting integers values (referring to the Enum index) or the string value themselves but obviously it doesn't work.

How would I go about handling this using (I assume) the AddTransformation method?

Answer 1

The solution was to create a new object and map the property manually. The Enum was handled this way:

MyEnumProperty = (MyEnumProperty)Convert.ToInt32(c["ColumnNameInExcel"])

Answer 2

I was able to accomplish this by mapping the value from the cell to the enum value in the transformation function:

excel.AddTransformation<DataImportJob>(x => x.Status, cellValue =>
{
    switch (cellValue)
    {
        case "Failed":
            return JobStatusType.Failed;
        case "InProgress":
            return JobStatusType.InProgress;
        case "Scheduled":
            return JobStatusType.Scheduled;
        case "Success":
            return JobStatusType.Success;
        default:
            return JobStatusType.Undefined;
    }
});

Answer 3

Yea, try the AddTransformation method and see if that works.

Answer 4

I tried the AddTransformation method with Invalid cast from Double to enum issue.

excelFile.AddTransformation<Table>(x => x.Company, cellValue => (MyEnumProperty)Convert.ToInt32(cellValue));
