Remarks

Use the HtmlTableRowCollection class to programmatically manage a collection of HtmlTableRow objects that represent the rows in an HtmlTable control. This class is commonly used to add, remove, or modify the contents of a row in an HtmlTable control.

Note

An HtmlTable control contains a Rows property that represents a collection of HtmlTableRow objects. Each HtmlTableRow represents an individual row in the table. An HtmlTableRow contains a Cells property that represents a collection of HtmlTableCell objects. These objects, in turn, represent the individual cells of the table. To retrieve an individual cell, first get the HtmlTableRow object, representing the row containing the cell, from the Rows collection of the HtmlTable control. You can then get the HtmlTableCell object, representing the cell in the row, from the Cells collection of the HtmlTableRow.

Properties

Count	Gets the number of HtmlTableRow objects in the HtmlTableRowCollection collection.
IsReadOnly	Gets a value indicating whether the HtmlTableRowCollection collection is read-only.
IsSynchronized	Gets a value indicating whether access to the HtmlTableRowCollection collection is synchronized (thread safe).
Item[Int32]	Gets the HtmlTableRow object at the specified index from the HtmlTableRowCollection collection.
SyncRoot	Gets the object that can be used to synchronize access to the HtmlTableRowCollection collection.

Methods

Add(HtmlTableRow)	Appends the specified HtmlTableRow object to the end of the HtmlTableRowCollection collection.
Clear()	Removes all HtmlTableRow objects from the HtmlTableRowCollection collection.
CopyTo(Array, Int32)	Copies the items from the HtmlTableRowCollection collection to the specified Array object, starting at the specified index in the array.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEnumerator()	Returns an IEnumerator-implemented object that contains all HtmlTableRow objects in the HtmlTableRowCollection collection.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
Insert(Int32, HtmlTableRow)	Adds an HtmlTableRow object to the specified location in the collection.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Remove(HtmlTableRow)	Removes the specified HtmlTableRow object from the HtmlTableRowCollection collection.
RemoveAt(Int32)	Removes the HtmlTableRow object at the specified index from the HtmlTableRowCollection collection.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Extension Methods

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
