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

[SerializableAttribute] 
public class XmlSchemaException : SystemException
/** @attribute SerializableAttribute() */ 
public class XmlSchemaException extends SystemException
SerializableAttribute 
public class XmlSchemaException extends SystemException
Not applicable.

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);
    }
}
