Overview

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

This rule has no associated code-style options.

Example

// 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.

#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.

[*.{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.

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