Returns detailed information about the schema exception.

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

[SerializableAttribute]
public class XmlSchemaException : SystemException

The XmlSchemaException type exposes the following members.

  NameDescription
Public methodSupported by the XNA FrameworkXmlSchemaException()Initializes a new instance of the XmlSchemaException class.
Public methodSupported by the XNA FrameworkXmlSchemaException(String)Initializes a new instance of the XmlSchemaException class with the exception message specified.
Protected methodXmlSchemaException(SerializationInfo, StreamingContext)Constructs a new XmlSchemaException object with the given SerializationInfo and StreamingContext information that contains all the properties of the XmlSchemaException.
Public methodSupported by the XNA FrameworkXmlSchemaException(String, Exception)Initializes a new instance of the XmlSchemaException class with the exception message and original Exception object that caused this exception specified.
Public methodSupported by the XNA FrameworkXmlSchemaException(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.

Public methodSupported by the XNA FrameworkGetBaseExceptionWhen overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
Public methodSupported by the XNA FrameworkGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetObjectDataStreams all the XmlSchemaException properties into the SerializationInfo class for the given StreamingContext. (Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).)

Security noteSecurity 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.

using System;
using System.Xml;
using System.Xml.Schema;
using System.IO;

public class ValidXSD
{
    public static int Main()
    {

        FileStream fs;
        XmlSchema schema;
        try
        {
            fs = new FileStream("example.xsd", FileMode.Open);
            schema = XmlSchema.Read(fs, new ValidationEventHandler(ShowCompileError));

            XmlSchemaSet schemaSet = new XmlSchemaSet();
            schemaSet.ValidationEventHandler += new ValidationEventHandler(ShowCompileError);
            schemaSet.Add(schema);
            schemaSet.Compile();

            XmlSchema compiledSchema = null;

            foreach (XmlSchema schema1 in schemaSet.Schemas())
            {
                compiledSchema = schema1;
            }

            schema = compiledSchema;

            if (schema.IsCompiled)
            {
                // Schema is successfully compiled.  
                // Do something with it here.

            }
            return 0;
        }
        catch (XmlSchemaException e)
        {
            Console.WriteLine("LineNumber = {0}", e.LineNumber);
            Console.WriteLine("LinePosition = {0}", e.LinePosition);
            Console.WriteLine("Message = {0}", e.Message);
            return -1;
        }

    }

    private static void ShowCompileError(object sender, ValidationEventArgs e)
    {
        Console.WriteLine("Validation Error: {0}", e.Message);
    }
}
