Saving Document stream after replacing text destroys file

Hello,

I am using the document.Range.Replace method to replace Text in a word document. Normally i prefer working with streams, but in this case working with stream destroy the file after replacing text in it.

I made a sample method:


public override void ApplyTextTest()
{
//First I use a regular file
string fileName = “C:\Temp\Test”;
Document doc = new Document(fileName + “.docx”);
doc.Range.Replace("##Company.CompanyPart.CompanyDesc##", “replace it”, new FindReplaceOptions());
doc.Range.Replace("##=US.TestFunct.CompanyCode##", “replace it too”, new FindReplaceOptions());
doc.Range.Replace("##=US.TestFunct.Auchschon##", “replace it also”, new FindReplaceOptions());
//i am saving the result into another file (could save it to the original file, which would also work)
doc.Save(fileName + “_replaced.docx”);
//this works fine

//now i take the origin file and open it in a stream
FileStream stream = new FileStream(fileName + “.docx”, FileMode.Open, FileAccess.ReadWrite);
try
{
doc = new Document(stream);
doc.Range.Replace("##Company.CompanyPart.CompanyDesc##", “replace it”, new FindReplaceOptions());
doc.Range.Replace("##=US.TestFunct.CompanyCode##", “replace it too”, new FindReplaceOptions());
doc.Range.Replace("##=US.TestFunct.Auchschon##", “replace it also”, new FindReplaceOptions());
//i am saving the changes to the original stream
doc.Save(stream, SaveFormat.Docx);
}
finally
{
stream.Close();
stream.Dispose();
}
//now the file is rendered unusable…
}

Am I doing something wrong?

Thanks in advance

Stefan

Hi Stefan,

Thanks for your inquiry. Please use following code example to fix this issue. Hope this helps you.

FileStream stream = new FileStream(MyDir + "input.docx", FileMode.Open, FileAccess.Read);

try

{

Document doc = new Document(stream);

stream.Close();

stream.Dispose();

doc.Range.Replace("##Company.CompanyPart.CompanyDesc##", "replace it", new FindReplaceOptions());

doc.Range.Replace("##=US.TestFunct.CompanyCode##", "replace it too", new FindReplaceOptions());

doc.Range.Replace("##=US.TestFunct.Auchschon##", "replace it also", new FindReplaceOptions());

stream = new FileStream(MyDir + " input.docx ", FileMode.Create, FileAccess.Write);

//i am saving the changes to the original stream

doc.Save(stream, SaveFormat.Docx);

}

finally

{

stream.Close();

stream.Dispose();

}

Hi Tahir,

thanks for the help. I didn´t think that I would have to user another stream as an output stream. Since I am not the one opening the source stream, I cannot close it.

I now use a “SaveStream” to save the result, set the sourcestream length to 0 and after that copy the savestream over the sourcestream.

That helped, thank for the hint.

Best regards

Stefan
