LastSavedTime

BuiltInDocumentProperties.LastSavedTime property

Gets or sets the time of the last save in UTC.

public DateTime LastSavedTime { get; set; }

Remarks

For documents originated from RTF format this property returns the local time of last save operation.

Aspose.Words does not update this property.

Examples

Shows how to work with document properties in the “Origin” category.

// Open a document that we have created and edited using Microsoft Word.
Document doc = new Document(MyDir + "Properties.docx");
BuiltInDocumentProperties properties = doc.BuiltInDocumentProperties;

// The following built-in properties contain information regarding the creation and editing of this document.
// We can right-click this document in Windows Explorer and find
// these properties via "Properties" -> "Details" -> "Origin" category.
// Fields such as PRINTDATE and EDITTIME can display these values in the document body.
Console.WriteLine($"Created using {properties.NameOfApplication}, on {properties.CreatedTime}");
Console.WriteLine($"Minutes spent editing: {properties.TotalEditingTime}");
Console.WriteLine($"Date/time last printed: {properties.LastPrinted}");
Console.WriteLine($"Template document: {properties.Template}");

// We can also change the values of built-in properties.
properties.Company = "Doe Ltd.";
properties.Manager = "Jane Doe";
properties.Version = 5;
properties.RevisionNumber++;

// Microsoft Word updates the following properties automatically when we save the document.
// To use these properties with Aspose.Words, we will need to set values for them manually.
properties.LastSavedBy = "John Doe";
properties.LastSavedTime = DateTime.Now;

// We can right-click this document in Windows Explorer and find these properties in "Properties" -> "Details" -> "Origin".
doc.Save(ArtifactsDir + "DocumentProperties.Origin.docx");

Shows how to use the SAVEDATE field to display the date/time of the document’s most recent save operation performed using Microsoft Word.

Document doc = new Document(MyDir + "Document.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd();
builder.Writeln(" Date this document was last saved:");

// We can use the SAVEDATE field to display the last save operation's date and time on the document.
// The save operation that these fields refer to is the manual save in an application like Microsoft Word,
// not the document's Save method.
// Below are three different calendar types according to which the SAVEDATE field can display the date/time.
// 1 -  Islamic Lunar Calendar:
builder.Write("According to the Lunar Calendar - ");
FieldSaveDate field = (FieldSaveDate)builder.InsertField(FieldType.FieldSaveDate, true);
field.UseLunarCalendar = true;

Assert.AreEqual(" SAVEDATE  \\h", field.GetFieldCode());

// 2 -  Umm al-Qura calendar:
builder.Write("\nAccording to the Umm al-Qura calendar - ");
field = (FieldSaveDate)builder.InsertField(FieldType.FieldSaveDate, true);
field.UseUmAlQuraCalendar = true;

Assert.AreEqual(" SAVEDATE  \\u", field.GetFieldCode());

// 3 -  Indian National calendar:
builder.Write("\nAccording to the Indian National calendar - ");
field = (FieldSaveDate)builder.InsertField(FieldType.FieldSaveDate, true);
field.UseSakaEraCalendar = true;

Assert.AreEqual(" SAVEDATE  \\s", field.GetFieldCode());

// The SAVEDATE fields draw their date/time values from the LastSavedTime built-in property.
// The document's Save method will not update this value, but we can still update it manually.
doc.BuiltInDocumentProperties.LastSavedTime = DateTime.Now;

doc.UpdateFields();
doc.Save(ArtifactsDir + "Field.SAVEDATE.docx");
