Verify that a column exists in the DataRow before reading its value

Question

How do I write code that reads a DataRow but, if filed in DataRow isn't there, it just skips it and moves on, like this for example:

string BarcodeIssueUnit; if (dr_art_line["BarcodeIssueUnit"].ToString().Length <= 0) {     BarcodeIssueUnit = ""; } else {     BarcodeIssueUnit = dr_art_line["BarcodeIssueUnit"].ToString(); } 

Now, the Column BarcodeIssueUnit can belong to the table but, in some cases, that column does not exist in the table. If it's not there and I read it, I get this error:

System.ArgumentException: Column `BarcodeIssueUnit`  does not belong to table Line. 

I just want to run a check if the column is there ok, let see the values, if it's not, just skip that part and go on.

Check for column name using DataRow.Table.Columns. If there convert value else come out.

BarcodeIssueUnit = dr_art_line.Table.Columns.Contains("BarcodeIssueUnit")?                    dr_art_line["BarcodeIssueUnit"].ToString(): "";
