 		When adding to [code]msgids_context_plural[/code], you must add the data using the format [code]["A", "B", "C"][/code], where [code]A[/code] represents the extracted string, [code]B[/code] represents the context, and [code]C[/code] represents the plural version of the extracted string. If you want to add only context but not plural, put [code]""[/code] for the plural slot. The idea is the same if you only want to add plural but not context. See the code below for concrete examples.
 		The extracted strings will be written into a POT file selected by user under "POT Generation" in "Localization" tab in "Project Settings" menu.
 		Below shows an example of a custom parser that extracts strings from a CSV file to write into a POT.

 		To add a translatable string associated with context or plural, add it to [code]msgids_context_plural[/code]:
-		[codeblock]
+		[codeblocks]
+		[gdscript]
 		# This will add a message with msgid "Test 1", msgctxt "context", and msgid_plural "test 1 plurals".
 		msgids_context_plural.append(["Test 1", "context", "test 1 plurals"])
 		# This will add a message with msgid "A test without context" and msgid_plural "plurals".
 		msgids_context_plural.append(["A test without context", "", "plurals"])
 		# This will add a message with msgid "Only with context" and msgctxt "a friendly context".
 		msgids_context_plural.append(["Only with context", "a friendly context", ""])
-		[/codeblock]
+		[/gdscript]
+		[csharp]
+		// This will add a message with msgid "Test 1", msgctxt "context", and msgid_plural "test 1 plurals".
+		msgidsContextPlural.Add(new Godot.Collections.Array{"Test 1", "context", "test 1 Plurals"});
+		// This will add a message with msgid "A test without context" and msgid_plural "plurals".
+		msgidsContextPlural.Add(new Godot.Collections.Array{"A test without context", "", "plurals"});
+		// This will add a message with msgid "Only with context" and msgctxt "a friendly context".
+		msgidsContextPlural.Add(new Godot.Collections.Array{"Only with context", "a friendly context", ""});
+		[/csharp]
+		[/codeblocks]
 		[b]Note:[/b] If you override parsing logic for standard script types (GDScript, C#, etc.), it would be better to load the [code]path[/code] argument using [method ResourceLoader.load]. This is because built-in scripts are loaded as [Resource] type, not [File] type.
 		For example:
-		[codeblock]
+		[codeblocks]
+		[gdscript]
 		func parse_file(path, msgids, msgids_context_plural):
 		    var res = ResourceLoader.load(path, "Script")
-		    var text = res.get_source_code()
+		    var text = res.source_code
 		    # Parsing logic.
 
-
 		func get_recognized_extensions():
 		    return ["gd"]
-		[/codeblock]
+		[/gdscript]
+		[csharp]
+		public override void ParseFile(string path, Godot.Collections.Array msgids, Godot.Collections.Array msgidsContextPlural)
+		{
+		    var res = ResourceLoader.Load<Script>(path, "Script");
+		    string text = res.SourceCode;
+		    // Parsing logic.
+		}
+
+		public override Godot.Collections.Array GetRecognizedExtensions()
+		{
+		    return new Godot.Collections.Array{"gd"};
+		}
+		[/csharp]
+		[/codeblocks]
