LINQ中foreach的多重选择

Question

I have a foreach loop with DataSet ( ds ), CsvFileData is a generic type having three fields: InvestmentAgaID , InvestmentCode , HasPosition which are string s. CSVDataList is a list of CsvFileData .

Now I want to convert it into LINQ rather than foreach .

foreach (DataRow drow in ds.Tables[0].Rows)
{
    CsvFileData ob = new CsvFileData();

    ob.InvestmentAgaID = drow[1].ToString().Trim();
    ob.InvestmentCode = drow[0].ToString().Trim();
    ob.HasPosition = drow[2].ToString().Trim();
    CSVDataList.Add(ob);
}

Answer 1

Here it is:

var data = ds.Tables[0].Rows
.Cast<DataRow>()
.Select(x => new CsvFileData() 
{
    InvestmentAgaID = x[1].ToString().Trim(),
    InvestmentCode = x[0].ToString().Trim(),
    HasPosition = x[2].ToString().Trim()
})
.ToList();
