ServerDocument Constructor (Stream, String)

ServerDocument Constructor (Stream, String)

Initializes a new instance of the ServerDocument class using a stream that represents the document to be loaded and the file name extension of the document.

Namespace:  Microsoft.VisualStudio.Tools.Applications
Assembly:  Microsoft.VisualStudio.Tools.Applications.ServerDocument (in Microsoft.VisualStudio.Tools.Applications.ServerDocument.dll)

public ServerDocument(
	Stream stream,
	string fileType
)

Parameters

stream
Type: System.IO.Stream
A stream that represents the document to be loaded.
fileType
Type: System.String
The file name extension of the document that is stored in the bytes parameter, preceded by a period (.)—for example, ".xlsx" or ".docx".

ExceptionCondition
ArgumentNullException

The stream parameter is null or empty.

-or-

The fileType parameter is null or empty or consists entirely of white space characters.

ArgumentException

The stream parameter has zero length or its current position is at the stream's end.

UnknownCustomizationFileException

The fileType parameter specifies a file name extension that is not supported by the Visual Studio Tools for Office runtime.

DocumentCustomizedWithPreviousRuntimeException

The file specified by documentPath has a customization that was not created with the Visual Studio 2010 Tools for Office Runtime or the Visual Studio Tools for the Microsoft Office system (version 3.0 Runtime).

Use this constructor to access the cached data or deployment manifest information in a document that is already in memory. When you use this constructor, the document is opened with read/write access.

The fileType parameter is used only to determine the type of document that is stored in the byte array. The value of fileType is mapped to one of the file types that are supported for document-level customizations. No attempt is made to open the file. You can optionally pass in a complete file name (for example, "Workbook1.xlsx"), but if you do this, only the file name extension is used. For more information about the supported file types, see Architecture of Document-Level Customizations.

To access the byte array for the document after calling this constructor, use the Document property.

The following code example uses the ServerDocument(Stream, String) constructor to create a new ServerDocument from a FileStream that contains an Excel workbook with the .xlsx file name extension. The code then displays the URL of the deployment manifest for the customization that is attached to the document.

This example requires:

  • A console application project or some other non-Office project.

  • References to the following assemblies:

    • Microsoft.VisualStudio.Tools.Applications.ServerDocument.dll and Microsoft.VisualStudio.Tools.Applications.Runtime.dll (if the project targets the .NET Framework 4).

      or

    • Microsoft.VisualStudio.Tools.Applications.ServerDocument.v10.0.dll and Microsoft.VisualStudio.Tools.Applications.Runtime.v9.0.dll (if the project targets the .NET Framework 3.5).

  • Imports (for Visual Basic) or using (for C#) statements for Microsoft.VisualStudio.Tools.Applications and Microsoft.VisualStudio.Tools.Applications.Runtime namespaces at the top of your code file.


private void CreateServerDocumentFromStream(string documentPath)
{
    int runtimeVersion = 0;
    ServerDocument serverDocument1 = null;
    System.IO.FileStream stream = null;

    try
    {
        runtimeVersion = ServerDocument.GetCustomizationVersion(documentPath);
        if (runtimeVersion == 3)
        {
            stream = new System.IO.FileStream(
                documentPath, System.IO.FileMode.Open);
            serverDocument1 = new ServerDocument(stream,
                "*.xlsx");
            MessageBox.Show("The URL of the deployment manifest is: \n" +
                serverDocument1.DeploymentManifestUrl.ToString());
        }
    }
    catch (System.IO.FileNotFoundException)
    {
        System.Windows.Forms.MessageBox.Show("The specified document does not exist.");
    }
    catch (UnknownCustomizationFileException)
    {
        System.Windows.Forms.MessageBox.Show("The specified document has a file " +
            "extension that is not supported by Visual Studio Tools for Office.");
    }
    finally
    {
        if (serverDocument1 != null)
            serverDocument1.Close();
        if (stream != null)
            stream.Close();
    }
}
