Print Tree

Extension method .PrintTree() prints a tree representation of IIdentity.

// Get type
Type type = typeof(string);
// Create identity
IIdentity id = IdentityAccessors.Default.TypeName.Create(type);
// Print to string
string print = id.PrintTree();
// Output
Console.WriteLine(print);

Prints nodes from tail towards root.

Name("String") → Namespace("System") → Version("6.0.0.0") → Library("System.Private.CoreLib") → PublicKeyToken(7cec85d7bea7798e) → Culture("neutral")

'format:' can be provided as argument. There are variations:

• PrintFormat.DefaultVeryLong
• PrintFormat.DefaultLong
• PrintFormat.Default
• PrintFormat.DefaultShort
• PrintFormat.DefaultVeryShort

string print = id.PrintTree(format: IdentityPrintTreeExtensions.PrintFormat.DefaultVeryShort);

"String" → "System" → "6.0.0.0" → "System.Private.CoreLib" → 7cec85d7bea7798e → "neutral"

.PrintTreeTo(TextWriter) prints directly to TextWriter such as Console.Out.

id.PrintTreeTo(Console.Out);

Components-property is printed as tree branches.

IIdentity id = new Identity<string>
{
    Label = "MyList",
    Part = IdentityParts.Name,
    LabelAccessor = LabelAccessors.Default.String,
    Components = new IIdentity[] {  
        IdentityAccessors.Default.TypeNameWithoutAssembly.Create(typeof(int))
    }
};

Name("MyList")
└── [0] Name("Int32") → Namespace("System")

TypeName identity accessor deconstructs generic types as branching components.

Type type = typeof(Dictionary<string, IList<int>>);
IIdentity id = IdentityAccessors.Default.TypeNameWithoutAssembly.Create(type);

Name("Dictionary`2") → Namespace("Generic") → Namespace("Collections") → Namespace("System")
├── [0] Name("String") → Namespace("System")
└── [1] Name("IList`1") → Namespace("Generic") → Namespace("Collections") → Namespace("System")
        └── [0] Name("Int32") → Namespace("System")

.VisitTree() extension methods visits tree branches.

// Get type
Type type = typeof(Dictionary<string, IList<int>>);
// Create identity
IIdentity id = IdentityAccessors.Default.TypeName.Create(type);
// Visit tree branches
foreach (var line in id.VisitTree())
{
    // Visit nodes
    foreach (var node in line.Identity.GetParts())
    {
        // Print line
        Console.WriteLine($"{line.Level} {node.Part} {node.LabelObject}");
    }
}
