Examples

The following example shows the use of the XmlSchemaException class.

C#
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);
    }
}

Remarks

重要

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.

Constructors

XmlSchemaException()

Initializes a new instance of the XmlSchemaException class.

XmlSchemaException(SerializationInfo, StreamingContext)
Obsolete.

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

XmlSchemaException(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.

XmlSchemaException(String, Exception)

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

XmlSchemaException(String)

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