    <p>I have a table with many values inside of it that might have single quotes around them. I need to create a duplicate table without those single quotes. I can't modify the original table as I need to use it, 'as-is' later.</p> <p>I've done this with a table.Clone and using a foreach to loop through the rows and columns removing single quotes as I need and then putting that new row into the new table. It works and it's straight forward.....but</p> <p>I'd like to do the same thing using LINQ. This was my attempt....</p> <pre><code> Dim myResults = From myRow In dtTable _ From myItem In myRow.ItemArray _ Where TypeOf myItem Is String AndAlso _ myItem.ToString.StartsWith("'"c) AndAlso _ myItem.ToString.EndsWith("'"c) </code></pre> <p>As you can see - I didn't get very far. I had trouble finding examples that weren't looking at a specific column in the DataRow. It looks like my code does pull back all the matching results - but I'm at a lose for how I can create a duplicate table/modify the values?</p> <p>EDIT - I've started a bounty for this in the hopes that someone can provide a solution. The only requirement is to not using a For Each; as I already know how to do that. I've gotten closer - but I still can't seem to create a new row or a new table.</p> <p>My new approach hits a dead-end when I try to do this:</p> <pre><code>Dim MyNewRow As New Data.DataRow With {.ItemArray = myRemovedQuotes.ToArray} </code></pre> <p>The Error message I get says, "Error 1 'System.Data.DataRow.Protected Friend Sub New(builder As System.Data.DataRowBuilder)' is not accessible in this context because it is 'Protected Friend'."</p>

    1. COPlease tell me you're not doing this in an effort to prevent sql injection! It's just the wrong way to go about it.

    3. COI posted an answer in C#, but deleted it seeing the VB.NET tag; the problem is converting the object[] while keeping each row separate; I used Array.ConvertAll in the example.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
