Namespace: Microsoft.VisualStudio.Text
Assembly: Microsoft.VisualStudio.Text.Data (in Microsoft.VisualStudio.Text.Data.dll)

)

abstract CreateAndLoadTextDocument :

        contentType:IContentType *

        characterSubstitutionsOccurred:bool byref -> ITextDocument

function CreateAndLoadTextDocument(
    filePath : String, 
    contentType : IContentType, 
    attemptUtf8Detection : boolean, 
    characterSubstitutionsOccurred : boolean
) : ITextDocument

Parameters

filePath
Type: System.String
The full path to the file to be loaded.

contentType
Type: Microsoft.VisualStudio.Utilities.IContentType
The IContentType for the ITextBuffer.

attemptUtf8Detection
Type: System.Boolean
Whether to attempt to load the document as a UTF-8 file.

characterSubstitutionsOccurred
Type: System.Boolean%
[out] Set to true if some of the file bytes could not be directly translated using the given encoding.

Return Value

Type: Microsoft.VisualStudio.Text.ITextDocument
The ITextDocument.

Exceptions

Exception	Condition
ArgumentNullException	filePath or contentType is nulla null reference (Nothing in Visual Basic).

Remarks

The Visual Studio implementation of this method detects file encoding as follows:

If there is a byte order mark, then use the corresponding encoding.
Otherwise, iterate through the IEncodingDetector objects that match the contentType parameter until one returns a non-null Encoding value, and use that encoding.
If no encoding was detected, and the attemptUtf8Detection flag is set, and the stream can be decoded as UTF8 but not ASCII, then use UTF8.
Otherwise, use the system default encoding.
