How do I use lambda expressions to filter DataRows?

Question

How can I search rows in a datatable for a row with Col1=\"MyValue\"

I\'m thinking something like

Assert.IsTrue(dataSet.Tables[0].Rows.
    FindAll(x =&g

You can use the Select method of the data table to do this, or the Filter Property of the DefaultDataView on the table.

For the Select method:

var rows = dataSet.Tables[0].Select("Col1 = 'MyValue'");

For the DefaultView Filter:

dataSet.Tables[0].DefaultView.Fitler = "Col1 = 'MyValue'";
foreach (var drv in dataSet.Tables[0].DefaultView)
{
    // Do your processing
}
