Property Value
Rule ID IDE0050
Title Convert anonymous type to tuple
Category Style
Subcategory Language rules (expression-level preferences)
Applicable languages C# and Visual Basic

Overview

This rule recommends use of tuples over anonymous types, when the anonymous type has two or more fields.

Options

This rule has no associated code-style options.

Example

// Code with violations
var t1 = new { a = 1, b = 2 };

// Fixed code
var t1 = (a: 1, b: 2);

' Code with violations
Dim t1 = New With { .a = 1, .b = 2 }

' Fixed code
Dim t1 = (a:=1, b:=2)

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 IDE0050
// The code that's violating the rule is on this line.
#pragma warning restore IDE0050

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

[*.{cs,vb}]
dotnet_diagnostic.IDE0050.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
