V3173. Possible incorrect initialization of variable. Consider verifying the initializer.
The analyzer detected a potential error that a variable or property initialization is missed.
Consider the example:
class A
{
int field1;
string field2;
string field3;
....
public void foo(int value)
{
field1 = value;
field2 = // <=
field3 = GetInitialization(value);
}
}In this case, the developer postponed the 'field2' initialization hoping that the code wouldn't compile and thus would remind of a missed initialization. But the code compiled successfully. 'field2' is assigned the value of 'field3'.
A similar situation may occur during a declaration, such as:
int b, c;
int a =
b = c = 2;This code looks suspicious. It is unclear what the author wanted to use to initialize the 'a' variable.
The analyzer will not issue a warning in a number of cases where it is clear that the code is written this way on purpose.
For example, there is indentation relative to the first line:
var1 =
var2 = 100;Here is another example with no indentation, but the value is written in several variables in the same way:
var1 =
var2 =
var3 =
var4 = 100;Was this page helpful?
