DebuggerStepThroughAttribute Class

Definition

Namespace:

System.Diagnostics

Assembly:

System.Runtime.dll

Source:

DebuggerStepThroughAttribute.cs

Instructs the debugger to step through the code instead of stepping into the code. This class cannot be inherited.

public ref class DebuggerStepThroughAttribute sealed : Attribute

[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.Struct, Inherited=false)]
public sealed class DebuggerStepThroughAttribute : Attribute

[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.Struct, Inherited=false)>]
type DebuggerStepThroughAttribute = class
    inherit Attribute

Remarks

This attribute is provided for use by source code debuggers; the common language runtime is not affected by it. For example, the Visual Studio debugger does not stop in a method that is marked with this attribute even if a breakpoint is set in the method.

The DebuggerStepThroughAttribute attribute affects the Just My Code (JMC) feature of Visual Studio in the following ways:

• If JMC is enabled, the Visual Studio debugger will not stop at a breakpoint in a method marked with the DebuggerStepThroughAttribute attribute.

• If JMC is disabled, the debugger stops at the breakpoint even if the method is marked with the DebuggerStepThroughAttribute.

The following code shows how the Visual Basic compiler uses the attribute.

<System.Diagnostics.DebuggerStepThrough()> _  
    Private Sub InitializeComponent()  
        components = New System.ComponentModel.Container()  
        Me.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font  
        Me.Text = "Form1"  
    End Sub  

This attribute avoids having to step into compiler-provided code and only steps into developer-provided code. For example, if you are stepping through code by using the F11 (Step Into) key, the attribute will cause the step to behave like an F10 (Step Over) key for compiler-provided code. The method won't be stepped into, but it will be executed.

Constructors

DebuggerStepThroughAttribute()

Initializes a new instance of the DebuggerStepThroughAttribute class.

Properties

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
