AvoidUnneededFieldInitializationRule

Assembly: Gendarme.Rules.Performance
Version: git

Description

This rule looks for constructors that assign fields to their default value (e.g. 0 for an integer, null for an object or a string). Since the CLR zero initializes all values there is no need, under most circumstances, to assign default values. Doing so only adds size to source code and in IL.

Examples

Bad example:

public class Bad {
    int i;
    string s;
    public Bad ()
    {
        i = 0;
        s = null;
    }
}

Good example:

public class Good {
    int i;
    string s;
    public Good ()
    {
        // don't assign 'i' since it's already 0
        // but we might prefer to assign a string to String.Empty
        s = String.Empty;
    }
}

Notes

• This rule is available since Gendarme 2.2
