To dump with extension methods, please install a separate VarDump.Extensions package.
Dump Extension methods:
using System;
using System.Linq;
var dictionary = new[]
{
new
{
Name = "Name1",
Surname = "Surname1"
}
}.ToDictionary(x => x.Name, x => x);
Console.WriteLine(dictionary.DumpText());
dictionary.DumpConsole();
dictionary.DumpDebug();
dictionary.DumpTrace();
Dump Extension methods, how to switch default dumper to VB:
using System;
using System.Linq;
VarDumpExtensions.VarDumpFactory = VarDumpFactories.VisualBasic;
var dictionary = new[]
{
new
{
Name = "Name1",
Surname = "Surname1"
}
}.ToDictionary(x => x.Name, x => x);
Console.WriteLine(dictionary.DumpText());
dictionary.DumpConsole();
dictionary.DumpDebug();
dictionary.DumpTrace();
Extensibility:
With middleware:
using System;
using VarDump;
using VarDump.Visitor;
using VarDump.Visitor.Descriptors;
using VarDump.Visitor.Descriptors.Specific;
// For more examples see https://github.com/ycherkes/VarDump/blob/main/test/VarDump.UnitTests/ObjectDescriptorMiddlewareSpec.cs
var obj = new
{
FullName = "BRUCE LEE",
CardNumber = "4953089013607",
OtherInfo = new
{
CardNumber = "5201294442453002",
}
};
var options = new DumpOptions
{
Descriptors =
{
new ObjectContentReplacer { Replacement = MaskCardNumber }
}
};
var csDumper = new CSharpDumper(options);
var cs = csDumper.Dump(obj);
var vbDumper = new VisualBasicDumper(options);
var vb = vbDumper.Dump(obj);
// C# string
Console.WriteLine(cs);
// VB string
Console.WriteLine(vb);
static ReflectionDescription MaskCardNumber(ReflectionDescription description)
{
if (!IsCardNumber(description) || string.IsNullOrWhiteSpace((string)description.Value))
{
return description;
}
var stringValue = (string)description.Value;
var maskedValue = stringValue.Length - 4 > 0
? new string('*', stringValue.Length - 4) + stringValue.Substring(stringValue.Length - 4)
: stringValue;
return description with
{
Value = maskedValue
};
static bool IsCardNumber(ReflectionDescription description)
{
return description.Type == typeof(string)
&& description.Name?.EndsWith("cardnumber", StringComparison.OrdinalIgnoreCase) == true;
}
}
With KnownObjectVisitor:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.CompilerServices;
using VarDump;
using VarDump.CodeDom.Compiler;
using VarDump.Visitor;
// For more examples see https://github.com/ycherkes/VarDump/blob/main/test/VarDump.UnitTests/KnownObjectsSpec.cs
const string name = "World";
FormattableString str = $"Hello, {name}";
var options = new DumpOptions
{
ConfigureKnownObjects = (knownObjects, nextDepthVisitor, _, codeWriter) =>
{
knownObjects.Add(new FormattableStringVisitor(nextDepthVisitor, codeWriter));
}
};
var dumper = new CSharpDumper(options);
var result = dumper.Dump(str);
Console.WriteLine(result);
return;
class FormattableStringVisitor(INextDepthVisitor nextDepthVisitor, ICodeWriter codeWriter) : IKnownObjectVisitor
{
public string Id => nameof(FormattableString);
public bool IsSuitableFor(object obj, Type objectType)
{
return obj is FormattableString;
}
public void ConfigureOptions(Action<DumpOptions> configure)
{
}
public void Visit(object obj, Type objectType, VisitContext context)
{
var formattableString = (FormattableString)obj;
IEnumerable<Action> arguments =
[
() => codeWriter.WritePrimitive(formattableString.Format)
];
arguments = arguments.Concat(formattableString.GetArguments().Select(a => (Action)(() => nextDepthVisitor.Visit(a, context))));
codeWriter.WriteMethodInvoke(() =>
codeWriter.WriteMethodReference(
() => codeWriter.WriteType(typeof(FormattableStringFactory)),
nameof(FormattableStringFactory.Create)),
arguments);
}
}
