C# read xml file to memorystream

You may also want to consider using a StringWriter instead The following code demonstrates how to get the content of the memory buffer as a UTF8 encoded string. Note: ToArray is simpler to use than GetBuffer because ToArray returns the exact length of the stream, rather than the buffer size which might be larger than the stream content.

ToArray makes a copy of the bytes. Note: GetBuffer is more performant than ToArray , as it doesn't make a copy of the bytes. You do need to take care about possible undefined trailing bytes at the end of the buffer by considering the stream length rather than the buffer size.

Using GetBuffer is strongly advised if stream size is larger than bytes because the ToArray copy would be allocated on the Large Object Heap where it's lifetime can become problematic. It is also possible to clone the original MemoryStream as follows, to facilitate accessing it via a StreamReader e.

The ideal solution is to access the original MemoryStream before it has been closed, if possible. Just a wild guess: maybe you need to flush the streamwriter? Possibly the system sees that there are writes "pending". By flushing you know for sure that the stream contains all written characters and is readable.

In more traditional Open XML applications, you may want to open an Open XML document, do some temporary transformations on the document, such as accept all revisions, and then query the transformed document. In this case, you do not want to serialize the modified document back to the file system, as the temporary modifications to the document are for your convenience in querying the document, and not intended to be permanent.

In this case, you want to make an in-memory copy of the document, transform the in-memory copy, query it, and then close the document without serializing the modified document. This article describes the various approaches to working with documents in memory. There is one important point to make about this method: you must supply a resizable memory stream to this method. You often have to create a resizable memory stream from a byte array, or you must create a resizable memory stream from a non-resizable memory stream.

When working with the SharePoint Products and Technologies object models, you retrieve documents from a document library as a byte array, and there is a MemoryStream constructor that can create a memory stream from a byte array. However, this constructor creates a non-resizable memory stream. Instead, you must create a MemoryStream object using a constructor that takes no arguments, and then write the byte array to the newly created memory stream. The following example shows how to create a resizable memory stream from a byte array.

It creates a memory stream from a byte array. When working with the SharePoint Foundation Managed Client object model, you retrieve documents from a document library as a non-resizable memory stream.
