XmlSchemaException Class


Returns detailed information about the schema exception.

Namespace:   System.Xml.Schema
Assembly:  System.Xml (in System.Xml.dll)


Public Class XmlSchemaException
	Inherits SystemException


Initializes a new instance of the XmlSchemaException class.

System_CAPS_protmethodXmlSchemaException(SerializationInfo, StreamingContext)

Constructs a new XmlSchemaException object with the given SerializationInfo and StreamingContext information that contains all the properties of the XmlSchemaException.


Initializes a new instance of the XmlSchemaException class with the exception message specified.

System_CAPS_pubmethodXmlSchemaException(String, Exception)

Initializes a new instance of the XmlSchemaException class with the exception message and original Exception object that caused this exception specified.

System_CAPS_pubmethodXmlSchemaException(String, Exception, Int32, Int32)

Initializes a new instance of the XmlSchemaException class with the exception message specified, and the original Exception object, line number, and line position of the XML that cause this exception specified.


Gets a collection of key/value pairs that provide additional user-defined information about the exception.(Inherited from Exception.)


Gets or sets a link to the help file associated with this exception.(Inherited from Exception.)


Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception.(Inherited from Exception.)


Gets the Exception instance that caused the current exception.(Inherited from Exception.)


Gets the line number indicating where the error occurred.


Gets the line position indicating where the error occurred.


Gets the description of the error condition of this exception.(Overrides Exception.Message.)


Gets or sets the name of the application or the object that causes the error.(Inherited from Exception.)


The XmlSchemaObject that produced the XmlSchemaException.


Gets the Uniform Resource Identifier (URI) location of the schema that caused the exception.


Gets a string representation of the immediate frames on the call stack.(Inherited from Exception.)


Gets the method that throws the current exception.(Inherited from Exception.)


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


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


When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)


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

System_CAPS_pubmethodGetObjectData(SerializationInfo, StreamingContext)

Streams all the XmlSchemaException properties into the SerializationInfo class for the given StreamingContext.(Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).)


Gets the runtime type of the current instance.(Inherited from Exception.)


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


Creates and returns a string representation of the current exception.(Inherited from Exception.)


Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

System_CAPS_security Security Note

The XmlSchemaException class may contain sensitive information that should not be exposed in untrusted scenarios. For example, the SourceUri property returns the URI path to the schema file that caused the exception. The SourceUri property should not be exposed in untrusted scenarios. Exceptions should be properly handled so that this sensitive information is not exposed in untrusted scenarios.

The following example shows the use of the XmlSchemaException class.
