First, we all know that for the base class of private data or interface, regardless of the inheritance, this data forever belongs to this base class, only this one belongs to the object defined by this base class, of course, for this base class

Today review the C language type conversion and branching structure, C is a strong data type, and his grammar compiler is not as strict as other languages later, so we must pay attention to our own data type when using it. Type conversions are

1.int ival = 1; int &refval = ival;//reference must be initialized and type strictly match2.int ival = 1; int &refval = ival;int Const *REFVAL = &ival;//are equivalent, that is, the reference occupies the same memory space and pointer size 3.

1. PrefaceFor all the code examples in this article, if you are running on Windows compilation, you are using Visual Studio 2013. If the RHEL6.5 platform (Linux kernal:2.6.32-431.el6.i686) is compiled and run, its GCC version is 4.4.7 as

C # is a new programming language released by Microsoft in June 2000, primarily developed by Anders Heilsberg (Anders Hejlsberg), the first component-oriented programming language that compiles the source code into MSIL and then runs it. It draws on

Structure, enumeration, boxing, unboxing custom value types use structs to define new value types and make them behave like most predefined types, where the key is that any newly defined value types have their own data and methods. An enumeration is

The first condition to be met for a class to be traversed using foreach1, the class to implement public method common IEnumerator GetEnumerator () {}, you can also inherit the IEnumerable interface to implement this method2, the class implemented

Two DLLs are used here. One is Aspose.word.dll, the other is Icsharpcode.sharpziplib.dll,icsharpcode.sharpziplib.dll is used for bulk export of Word documents, by packaging the files into a compressed package, the output of the download file stream.

to get the relative path of the template when initializing Wordhelper. Gets the relative path of the document to be used in many places, such as batch export to save the file to the specified path, and then compress the package download, so

What's the Commission? A delegate is a type-safe object that points to another method (or methods) that will be called later in the program. In layman's words, a delegate is an object that can refer to a method, and when a delegate is created,

When sending a message in C #, there are times when the specified string does not match the form required by the topic .After looking up the data, the reason is that there are some special characters in your string that cause an error. Remove the
