Remove unreachable code (IDE0035)

  • מאמר
Property Value
Rule ID IDE0035
Title Remove unreachable code
Category Style
Subcategory Unnecessary code rules (expression-level preferences)
Applicable languages C# and Visual Basic

Overview

This rule flags executable code within methods and properties that can never be reached, and hence can be removed.

הערה

Even if you enable code style rules on build, this rule is not enabled. It only surfaces in the Visual Studio editor.

Options

This rule has no associated code-style options.

Example

C#‎ 
// Code with violations
void M()
{
    throw new System.Exception();

    // IDE0035: Remove unreachable code
    int v = 0;
}

// Fixed code
void M()
{
    throw new System.Exception();
}

Suppress a warning

If you want to suppress only a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

C#‎ 
#pragma warning disable IDE0035
// The code that's violating the rule is on this line.
#pragma warning restore IDE0035

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

ini 
[*.{cs,vb}]
dotnet_diagnostic.IDE0035.severity = none

To disable all of the code-style rules, set the severity for the category Style to none in the configuration file.

ini 
[*.{cs,vb}]
dotnet_analyzer_diagnostic.category-Style.severity = none
