C# - How to check if a column exists in a DataRow

It's a common requirement when you work with DataRows to check if a column exists. The next check would be if the column has a value which we will see afterwards in this post.

To check if a column exists:

dRow.Table.Columns["msisdn"] == null

The row doesn't contain a column property as such. Therefore you will have to get into the Parent table property to check into the columns in the row.

Note:
If the column doesn't exist,

dr["msisdn"] == null

will throw and error.

To check if a column has value and is not null value:

dr["msisdn"] == DBNull.Value

and

if(dr.IsNull("msisdn"))

are used to check if a column has value
