A colon within a C# element is not spaced correctly.
A violation of this rule occurs when the spacing around a colon is not correct.
The spacing around a colon depends upon the type of colon and how it is used within the code. A colon appearing within an element declaration must always have a single space on either side, unless it is the first or last character on the line. For example all of the colons below follow this rule:
public class Class2<T> : Class1 where T : MyType
public Class2(int x) : base(x)
When the colon comes at the end of a label or case statement, it must always be followed by whitespace or be the last character on the line, but should never be preceded by whitespace. For example:
Finally, when a colon is used within a conditional statement, it must always contain a single space on either side, unless the colon is the first or last character on the line. For example:
int x = y ? 2 : 3;
How to Fix Violations
To fix a violation of this rule, ensure that the spacing around the colon follows the rule described above.
