CompilerError Class

 

Represents a compiler error or warning.

Namespace:   System.CodeDom.Compiler
Assembly:  System (in System.dll)

System.Object
  System.CodeDom.Compiler.CompilerError
    System.Workflow.ComponentModel.Compiler.WorkflowCompilerError

<SerializableAttribute>
<PermissionSetAttribute(SecurityAction.InheritanceDemand, Name := "FullTrust")>
Public Class CompilerError

NameDescription
System_CAPS_pubmethodCompilerError()

Initializes a new instance of the CompilerError class.

System_CAPS_pubmethodCompilerError(String, Int32, Int32, String, String)

Initializes a new instance of the CompilerError class using the specified file name, line, column, error number, and error text.

NameDescription
System_CAPS_pubpropertyColumn

Gets or sets the column number where the source of the error occurs.

System_CAPS_pubpropertyErrorNumber

Gets or sets the error number.

System_CAPS_pubpropertyErrorText

Gets or sets the text of the error message.

System_CAPS_pubpropertyFileName

Gets or sets the file name of the source file that contains the code which caused the error.

System_CAPS_pubpropertyIsWarning

Gets or sets a value that indicates whether the error is a warning.

System_CAPS_pubpropertyLine

Gets or sets the line number where the source of the error occurs.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodToString()

Provides an implementation of Object's ToString method.(Overrides Object.ToString().)

CompilerError represents a compiler error or a warning that has been returned by the compiler.

System_CAPS_noteNote

This class contains an inheritance demand at the class level that applies to all members. A SecurityException is thrown when the derived class does not have full-trust permission. For details about inheritance demands, see Inheritance Demands.

The following example compiles a CodeDOM program graph and provides an example of how to programmatically access CompilerError data.
