Example

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

class Program
{
    static void Main()
    {
        var schemaSet = new XmlSchemaSet();
        try
        {
            schemaSet.Add(null, "invalidSchema.xsd"); // will trigger integrity error
            schemaSet.Compile();
        }
        catch (XmlSchemaIntegrityValidationException ex)
        {
            Console.WriteLine($"Integrity error: {ex.Message}");
            Console.WriteLine($"Source: {ex.SourceUri}");
            Console.WriteLine($"Location: line {ex.LineNumber}, pos {ex.LinePosition}");
        }
    }
}

Remarks

This exception is thrown only when schema validation is performed with integrity checks enabled (e.g., when using XmlReaderSettings.Schemas with ValidationFlags.ReportValidationWarnings and XmlSchemaObjectTable verification).
