One columned datatable to List<string> in C#

One columned datatable to List<string> in C#

You can convert a single column of a DataTable to a List<string> in C# by iterating through each row of the DataTable, accessing the value of the desired column, and adding it to a new List<string> object. Here's an example:

// Assuming you have a DataTable named 'table' and the desired column is named 'column' List<string> columnList = new List<string>(); foreach (DataRow row in table.Rows) { string value = row["column"].ToString(); columnList.Add(value); }

In this example, we create a new List<string> object named columnList. We then iterate through each row in the DataTable using a foreach loop, and access the value of the desired column by using the DataRow indexer with the name of the column ("column" in this case). We convert the value to a string using the ToString() method and add it to the columnList using the List<T>.Add method.

After the loop completes, columnList will contain all the values from the desired column of the DataTable as a List<string>.
