ReviewDoubleAssignmentRule

Assembly: Gendarme.Rules.Correctness
Version: 2.10

Description

This rule checks for variables or fields that are assigned multiple times using the same value. This won't change the value of the variable (or fields) but should be reviewed since it could be a typo that hides a real issue in the code.

Examples

Bad example:

public class Bad {
    private int x, y;
    public Bad (int value)
    {
        // x is assigned twice, but y is not assigned
        x = x = value;
    }
}

Good example:

public class Good {
    private int x, y;
    public Good (int value)
    {
        // x = y = value; was the original meaning but since it's confusing...
        x = value;
        y = value;
    }
}

Notes
