This is all overkill. Your exception should just override the Message Property. public override String Message { get { return base.Message + String.Format(“, HttpStatusCode={0}, RequestId='{1}'”, httpStatusCode, RequestId); } } The default ToString method for the Exception class is basically “ClassName: Message –> InnerException.ToString() StackTrace“. So overriding the Message puts your message text exactly where it … Read more
because you cannot call instance method ToString() on a null reference. And MessageBox.Show() is probably implemented to ignore null and print out empty message box.
You can do this easily with a custom JsonConverter: public class ToStringJsonConverter : JsonConverter { public override bool CanConvert(Type objectType) { return true; } public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { writer.WriteValue(value.ToString()); } public override bool CanRead { get { return false; } } public override object ReadJson(JsonReader reader, Type objectType, object … Read more
The additional parameter works only for Number.prototype.toString to specify the radix (integer between 2 and 36 specifying the base to use for representing numeric values): var number = 12345; number.toString(2) === “11000000111001” number.toString(3) === “121221020” // … number.toString(36) === “9ix”
To get a human-readable toString(), you must use Arrays.toString(), like this: System.out.println(Arrays.toString(Array)); Java’s toString() for an array is to print [, followed by a character representing the type of the array’s elements (in your case C for char), followed by @ then the “identity hash code” of the array (think of it like you would … Read more
You can use i.ToString(“D2”) or i.ToString(“00”) See Standard Numeric Format Strings and Custom Numeric Format Strings on Microsoft Docs for more details
Look like it is a multi thread issue. I locked the thread to prevent multi access to the stringBuilder at the same time. public void AddString(string s) { lock(this.LockObject) { StringBuilder.AppendLine(s); } }
myTimeSpan.ToString(@”hh\:mm”) Custom TimeSpan Format Strings The custom TimeSpan format specifiers do not include placeholder separator symbols, such as the symbols that separate days from hours, hours from minutes, or seconds from fractional seconds. Instead, these symbols must be included in the custom format string as string literals. For example, “dd.hh\:mm” defines a period (.) as … Read more
What harm do they do? Why remove them if you have them? I find toString() extremely useful when emitting debugging statements. Personally, I would always err on the side of having a workable toString() method. So little work to write.
