Following are naming conventions one should follow as best practice.

1.Use Pascal casing for Class names

public class HelloWorld
{
...
}

2. Use Pascal casing for Method names

void SayHello(string name)
{
...
}

3.Use Camel casing for variables and method parameters

int totalCount = 0;
void SayHello(string name)
{
string fullMessage = "Hello " + name;
...
}

4. Use the prefix “I” with Camel Casing for interfaces ( Example: IEntity )

5. Do not use Hungarian notation to name variables.

All variables should use camel casing.

6. Use Meaningful, descriptive words to name variables. Do not use abbreviations.

Good:

string address
int salary

Not Good:

string nam
string addr
int sal

7. Do not use single character variable names like i, n, s etc. Use names like index, temp

One exception in this case would be variables used for iterations in loops:

for ( int i = 0; i < count; i++ )
{
...
}

8. Do not use underscores (_) for local variable names.

9. All member variables must be prefixed with underscore (_) so that they can be identified from other local variables.

10. Do not use variable names that resemble keywords.
