// Insert two merge fields with German locale.
builder.Font.LocaleId = new CultureInfo("de-DE").LCID;
builder.InsertField("MERGEFIELD Date1 \\@ \"dddd, d MMMM yyyy\"");
builder.Write(" - ");
builder.InsertField("MERGEFIELD Date2 \\@ \"dddd, d MMMM yyyy\"");

// Set the current culture to US English after preserving its original value in a variable.
CultureInfo currentCulture = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");

// This merge will use the current thread's culture to format the date, US English.
doc.MailMerge.Execute(new[] { "Date1" }, new object[] { new DateTime(2020, 1, 01) });

// Configure the next merge to source its culture value from the field code. The value of that culture will be German.
doc.FieldOptions.FieldUpdateCultureSource = FieldUpdateCultureSource.FieldCode;
doc.MailMerge.Execute(new[] { "Date2" }, new object[] { new DateTime(2020, 1, 01) });
