person.xml:(不带命名空间)

    <?xml version="1.0" encoding="UTF-8"?>
    <Persons>
      <Person id="1">
        <Name>张三</Name>
        <Age>120</Age>
      </Person>
      <Person id="2">
        <Name>李四</Name>
        <Age>20</Age>
      </Person>
    </Persons>


person.xsd:

    <?xml version="1.0" encoding="UTF-8"?>
    <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
     
      <xs:annotation>

      </xs:annotation>
      <xs:element name="Persons">

            <xs:element name="Person" maxOccurs="unbounded">

                      <xs:restriction base="xs:string">

                      </xs:restriction>
                    </xs:simpleType>
                  </xs:element>

                <xs:attribute name="id" use="required">
                  <xs:simpleType>

验证方法：

            /// <summary>  
            /// 通过xsd验证xml格式是否正确，正确返回空字符串，错误返回提示  
            /// </summary>  
            /// <param name="xmlFile">xml文件</param>  
            /// <param name="xsdFile">xsd文件</param>  
            /// <param name="namespaceUrl">命名空间，无则默认为null</param>  
            /// <returns></returns>  
            public static string XmlValidationByXsd(string xmlFile, string xsdFile, string namespaceUrl = null)
            {
                StringBuilder sb = new StringBuilder();
                XmlReaderSettings settings = new XmlReaderSettings();
                settings.ValidationType = ValidationType.Schema;
                settings.Schemas.Add(namespaceUrl, xsdFile);
                //验证出错时执行
                settings.ValidationEventHandler += (x, y) =>
                {
                    sb.AppendFormat("{0}|", y.Message);
                };
                using (XmlReader reader = XmlReader.Create(xmlFile, settings))
                {
                    try
                    {
                        while (reader.Read()) ;
                    }
                    catch (XmlException ex)
                    {
                        sb.AppendFormat("{0}|",ex.Message);
                    }
                }
                return sb.ToString();
            }

上面代码是验证xml文件，如果是xml字符串，则可用下面：

               /// <summary>  
               /// 通过xsd验证xml格式是否正确，正确返回空字符串，错误返回提示  
               /// </summary>  
               /// <param name="xmlText">xml文本内容</param>  
               /// <param name="schemaFile">xsd文件</param>  
               /// <returns></returns>  
               public static string XmlValidateByXsd(string xmlText, string schemaFile)  
               {  
                   StringBuilder sb = new StringBuilder();  
                   XmlReaderSettings settings = new XmlReaderSettings();  
                   settings.ValidationType = ValidationType.Schema;  
                   settings.Schemas.Add(null, schemaFile);  
                   settings.ValidationEventHandler += (x, y) =>  
                   {  
                       sb.AppendFormat("{0}\n", y.Message);  
                   };  
                   using (XmlReader reader = XmlReader.Create(new StringReader(xmlText), settings))  
                   {  
                       try  
                       {  
                           while (reader.Read()) ;  
                       }  
                       catch (XmlException ex)  
                       {  
                           sb.AppendFormat("{0}\n", ex.Message);  
                       }  
                   }  
                   return sb.ToString();  
               }
