V3029. The conditional expressions of the 'if' statements situated alongside each other are identical.

The analyzer has detected two 'if' statements with identical conditions following each other. This code is either redundant or incorrect.

Consider the following example:

public void Logging(string S_1, string S_2)
{
  if (!String.IsNullOrEmpty(S_1))
    Print(S_1);
  if (!String.IsNullOrEmpty(S_1))
    Print(S_2);
}

There is an error in the second condition, where the 'S_1' variable is checked for the second time whereas it is variable 'S_2' that should be checked instead.

This is what the correct version of the code looks like:

public void Logging(string S_1, string S_2)
{
  if (!String.IsNullOrEmpty(S_1))
    Print(S_1);
  if (!String.IsNullOrEmpty(S_2))
    Print(S_2);
}

This diagnostic does not always point out a bug; often, it deals with just redundant code:

public void Logging2(bool toFile, string S_1, string S_2)
{
  if(toFile)
    Print(S_1);
  if (toFile)
    Print(S_2);
}

This code is correct but somewhat inefficient since it checks one and the same variable twice. We suggest rewriting it as follows:

public void Logging2(bool toFile, string S_1, string S_2)
{
  if(toFile)
  {
    Print(S_1);
    Print(S_2);
  }
}
