HttpRequest.InsertEntityBody Method (Byte[], Int32, Int32)

Provides IIS with a copy of the HTTP request entity body and with information about the request entity object.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

[AspNetHostingPermissionAttribute(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.High)]
public void InsertEntityBody(
	byte[] buffer,
	int offset,
	int count


Type: System.Byte[]
An array that contains the request entity data.
Type: System.Int32
The zero-based position in buffer at which to begin storing the request entity data.
Type: System.Int32
The number of bytes to read into the buffer array.


The method was invoked on a version of IIS earlier than IIS 7.0.


buffer is null.


count is a negative value.


offset is a negative value.


The number of items in count is larger than the available space in buffer, given the offset value.

IIS does not maintain a copy of the request after it has been read. Therefore, it is recommended that only the handler for an HTTP request should read the request entity.

The HttpRequest.InsertEntityBody method overload is useful when you want to perform custom processing, such as inserting a different entity body into memory.
