C# supports a strict Boolean veri type, bool. Statements that take conditions, such bey while and if, require an expression of a type that implements the true operator, such birli the Boolean type. While C++ also katışıksız a Boolean type, it sevimli be freely converted to and from integers, and expressions such bey if (a) require only that a is convertible to bool, allowing a to be an int, or a pointer.

In contrast, reference types have the notion of referential identity, meaning that each instance of a reference type is inherently distinct from every other instance, even if the data within both instances is the same. This is reflected in default equality and inequality comparisons for reference types, which sınav for referential rather than structural equality, unless the corresponding operators are overloaded (such as the case for System.String).

Bir numara satırdan oluşan bir if ve else bloğu varsa parantez içine hileınmasına ister yoktur. Amma kodun okunabilirliği açısından yinede bloklara yazmakta kâr var. Yukarıdaki kodların alternatifi şu şekilde olurdu:

When one or both operands are of type string, the + operator concatenates the string representations of its operands (the string representation of null is an empty string):

[24] Microsoft had considered keeping the name "Cool" birli the bitiş name of the language, but chose not to do so for trademark reasons. By the time the .Kupkuru project was publicly announced at the July 2000 c# switch case nedir Professional Developers Conference, the language had been renamed C#, and the class libraries and ASP.Kupkuru runtime had been ported to C#.

Instances of value types neither have referential identity nor referential comparison semantics. Equality and inequality comparisons for value types compare the actual veri values within the instances, unless the corresponding operators are overloaded. Value types are derived from System.ValueType, always have a default value, and sevimli always be created and copied. Some other limitations on value types are that they cannot derive from each other (but dirilik implement interfaces) and cannot have an explicit default (parameterless) constructor because they already have an implicit one which initializes all contained veri to the type-dependent default value (0, null, or alike).

Use the checked and unchecked statements to explicitly specify the overflow-checking context, birli the example at the beginning of this section demonstrates.

The syntax for handling exceptions is try something catch (Exception ex) handle ex finally do something whether or hamiş an exception occurred .

Remember that string are immutable and hayat't be GC'd. In short, if you use your code in a tight loop, you could end up wasting many megabytes of memory for no reason (this is why the StringBuilder class was created.)
