void SetFileExtension(
	string extension

The following code example shows a possible implementation for a custom host. This code example is part of a larger example. For the complete example, see Walkthrough: Creating a Custom Text Template Host.

//the host can provide a default by setting the value of the field here
private string fileExtensionValue = ".txt";
public string FileExtension
{
    get { return fileExtensionValue; }
}

public void SetFileExtension(string extension)
{
    //the parameter extension has a '.' in front of it already
    //--------------------------------------------------------
    fileExtensionValue = extension;
}
