What is the C# equivalent to Java's isInstance()?
The java.lang.Class.isInstance() determines if the specified Object is assignment-compatible with the object represented by this Class Java’s isInstance() method’s equivalent in C# is IsAssignableFrom(). Another simplest way for isInstance() equivalent is − bool res = (ob is DemoClass); You can also work with Type.IsInstanceOfType for the same result − ob.GetType().IsInstanceOfType(otherOb)
Read MoreC# equivalent to Java's Thread.setDaemon?
C# equivalent to Java's Thread.setDaemon is the concept of foreground and background threads. When the foreground threads will close, the background threads will be terminated. Foreground threads continue to run until the last foreground thread is terminated. The property used for background thread is IsBackground that gets or sets a value indicating whether a thread is a background thread. The default value of this property would be false because the default threads created are Foreground Threads. To make a thread Daemon in C#, use the isBackground − Thread bgThread = new Thread(tStart); bgThread.IsBackground = true; bgThread.Start();
Read MorePython program to check if there are K consecutive 1's in a binary number?
First we take a user input string with the combination of 1’s and 0’s.then create a new string with 1’s, then check if there is any p number of consecutive 1’s is present or not. If present then display FOUND otherwise NOTFOUND. Example Binary number ::1111001111 Enter consecutive 1’s :3 Consecutive 1's is Found Algorithm Step 1: input a string with the combination of 1’s, it’s stored in the variable X and 0’s and p is the consecutive 1’s in a binary number. Step 2: form a new string of p 1’s. newstring=”1”*p Step ...
Read MoreDifference between Abstract Class and Interface in C#
Interfaces define properties, methods, and events, which are the members of the interface. Interfaces contain only the declaration of the members. It is the responsibility of the deriving class to define the members. Abstract classes to some extent serve the same purpose, however, they are mostly used when only few methods are to be declared by the base class and the deriving class implements the functionalities. Let us now see the difference between Abstract class and Interface in C#. Inherit A class may inherit more than one interface, whereas a class may inherit only one abstract class. Member Field You ...
Read MoreDifference between Boxing and Unboxing in C#
Boxing convert value type to an object type whereas unboxing converts object type to the value type. Let us see the difference between Boxing and Unboxing in C#. Storage In boxing, the value stored on the stack is copied to the object stored on heap memory, whereas unboxing is the opposite. In Unboxing, the object's value stored on the heap memory is copied to the value type stored on stack. Conversion Unboxing has explicit conversion whereas boxing has implicit conversion. Example int a = 10; object obj = a; // boxing int b = (int) ob; // unboxing
Read MoreDifferences between C++ and C#
C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg. The following are the differences between C++and C#. Memory Management C++ has manual memory management, whereas memory management is handled automatically in C#. Platforms C++ can be run on different platforms whereas C# is generally used only on Windows. Faster code C++ code ...
Read MorePython program to check the validity of a Password?
Here given a password, our task is to check that this Password is valid or not. Here we use re module that provide regular expression and re.search() is used for checking the validation of alphabets, digits or special characters. Algorithm Step 1: first we take an alphanumeric string as a password. Step 2: first check that this string should minimum 8 characters. Step 3: the alphabets must be between a-z. Step 4: At least one alphabet should be in Uppercase A-Z. Step 5: At least 1 number or digit between 0-9. Step 6: At least 1 character from [_ ...

Python provides openpyxl module for operating with Excel files. How to create Excel files, how to write, read etc. can be implemented by this module. For installing openpyxl module, we can write this command in command prompt pip install openpyxl If we want to give a sheet title name Example code import openpyxl my_wb = openpyxl.Workbook() my_sheet = my_wb.active my_sheet_title = my_sheet.title print("My sheet title: " + my_sheet_title) Output My sheet title:Sheet To change Title Name Example code import openpyxl my_wb = openpyxl.Workbook() my_sheet = my_wb.active my_sheet.title = "My New Sheet" print("sheet name ...
Read MoreDifferences between C and C#
C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972. C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg. The following are the differences between C and C#. Language C language is a structured programming language, whereas C# is an object-orinted language. Memory Management C has manual memory management, whereas memory management is handled automatically in C#. Garbage Collection C do not have ...
Read MoreComparison between C# and .NET Framework
C# is a programming language and .NET framework is a software framework developed by Microsoft. .NET has Common Language Runtime (CLR), which is a virtual component of .NET framework. And framework is a large class of library. .NET not only has C#, but through it, you can work with VB, F#, etc. Programs written for .NET Framework execute in Common Language Runtime. .NET Framework supports development in C#. C# is a part of .NET and has the following features − Boolean Conditions Automatic Garbage Collection Standard Library Assembly Versioning Properties and Events Delegates and Events Management
