Input stream in mvc 4 asp.net

Question

See more:

for a web API in MVC 4 i'm trying to get the input stream of a http resquest post in the controller i'm always getting the length of the byte array = 53 but the byte array is empty so when i convert it to string i keep getting an empty string

this is what i'm using:

VB

Dim InStream As Stream
Dim Len As Integer
InStream = HttpContext.Current.Request.InputStream
InStream = CType(InStream, Stream)
Len = CInt(InStream.Length)
Dim ByteArray(Len) As Byte
InStream.Read(ByteArray, 0, Len)
Dim jsonParam As String
jsonParam = System.Text.Encoding.UTF8.GetString(ByteArray)

i think it's from this line :

VB

InStream = HttpContext.Current.Request.InputStream

but i did not find how to replace it

note that the string the client is sending is a JSON string

any help?

I found that the stream is at the end, i will have to set it to the beginning

VB

Dim InStream As Stream
Dim Len As Integer
InStream = HttpContext.Current.Request.InputStream
InStream = CType(InStream, Stream)
Len = CInt(InStream.Length)
Dim ByteArray(Len) As Byte
InStream.Seek(0, SeekOrigin.Begin);
InStream.Read(ByteArray, 0, Len)
Dim jsonParam As String
jsonParam = System.Text.Encoding.UTF8.GetString(ByteArray)
