Gets a copy of the vertex buffer data, specifying the starting offset, start index, number of elements, and vertex stride.

Syntax

'Declaration
Public Sub GetData(Of T As ValueType) ( _
         offsetInBytes As Integer, _
         data As T(), _
         startIndex As Integer, _
         elementCount As Integer, _
         vertexStride As Integer _
)

public void GetData<T> (
         int offsetInBytes,
         T[] data,
         int startIndex,
         int elementCount,
         int vertexStride
) where T : ValueType

public:
generic<typename T> where T : ValueType
void GetData(
         int offsetInBytes,
         T data[],
         int startIndex,
         int elementCount,
         int vertexStride
)

Type Parameters

T
The type of the elements in the array.

Parameters

offsetInBytes
Type: Int32
Offset in bytes from the beginning of the buffer to the data.
data
Type: T
Array of data.
startIndex
Type: Int32
Index of the first element to get.
elementCount
Type: Int32
Number of elements to get.
vertexStride
Type: Int32
Size, in bytes, of an element in the vertex buffer.

Exceptions

Exception type	Condition
ArgumentNullException	data is null. data must be of sufficient length to receive the data.
ArgumentOutOfRangeException	One of the following conditions is true: The vertex stride is larger than the vertex buffer. The vertex stride is too small for the type of data requested.
InvalidOperationException	The array is not the correct size for the amount of data requested.
NotSupportedException	This VertexBuffer was created with a usage type of BufferUsage.WriteOnly. Calling GetData on a resource that was created with BufferUsage.WriteOnly is not supported.
