V3136. Constant expression in switch statement.


The analyzer detected a constant expression in a 'switch' statement. This usually indicates the presence of a logic error in the code.

Consider the following synthetic example:

int i = 1;
switch (i)
{
  ....
}

The condition of the 'switch' statement is represented by a variable whose value can be computed at compilation time. This situation could have resulted from code refactoring: the previous version of the code changed the variable's value but then it was modified and the variable turned out to be no longer assigned any value.

According to Common Weakness Enumeration, potential errors found by using this diagnostic are classified as CWE-691.

You can look at examples of errors detected by the V3136 diagnostic.
