C# Coding Standard - Naming Conventions and Style
Naming Conventions and Style
Use Pascal casing for type and method names and constants:
User camel casing for local variable names and method arguments:
void MyMethod(int someNumber)
{
int number;
}
Prefix interface names with I
Interface IMyInterfance
{
…
}
Prefix private member variables with m_. Use Pascal casing for the rest of a member variable name following the m_.
public class SomeClass
{
private int m_Number;
}
Suffix customs attribute classes with Attribute.
public class TagColumnAttribute : Attribute
{
…
}
Suffix customs exception classes with Exception
public class CEWorkstationException:Exception
{
…
}
Name methods using web-object pair
Such as: ShowExamTrackingDialog();
Methods with return values should have a name describing the value returned.
Such as: GetRequestedReportState()
Use descriptive variable names.
a) Avoid single character variable names
// void
int i;
int t;
// instead
int index;
int temp;
b) Avoid using Hungarian notation for public or protected members
c) Do not abbreviate words
// void
int num;
// instead
int number;
Always use C# predefined types rather than the aliases in the System namespace.

Not Use |
|
object obj; |
Object obj; |
|
string strConnection; |
String strConnection; |
|
int index; |
Int32 index; |
With generics, use capital letters for types. Reserve suffixing Type when dealing with the .NET type Type.
// Correct
public class LinkedList<K,T>
{
…
}
// Avoid
public class LinkedList<KeyType,DataType>
{
…
}
Use meaningful namespace
CEWorkstation.Resource
Avoid fully qualified type names. Use the using statement instead.
using CEWorkstation.Resource
Avoid putting a using statement inside a namespace.
namespace CEWorksation.Resource
{
using System;
using System.Data;
using System.Web;
}
