C＃错误XMLSchema验证。 “类型字符串没有被宣布为”

Question

我有一个看起来像我想验证XML这个

<?xml version="1.0" encoding="UTF-8"?> 
<!-- FCT Automated Data Transfer Configuration --> 
<config_info> 
    <!--First Server --> 
    <transfer_configuration ID="1"> 
    <target_info> 
     <connection_string>Data Source=xyz;Initial Catalog=abc; User id=123; Password=Welcome1;</connection_string> 
     <table_name>t1234</table_name> 
    </target_info> 
    <source_info> 
     <access_file_path>Provider= Microsoft Office 12.0 Access Database Engine OLE DB Provider ; Data Source=C:\Data\Data.accdb</access_file_path> 
     <table_name>Data</table_name> 
    </source_info> 
    <transfer_interval_hours>240</transfer_interval_hours> 
    <retry_interval_minutes>100</retry_interval_minutes> 
    <transfer_interval_hours>0</transfer_interval_hours> 
    <field_map> 
     <Field source="Test_DateTime" target="Test_DateTime" /> 
     <Field source="UUT_SlotNumber" target="UUT_SlotNumber" /> 
     <Field source="System_ID" target="System_ID" />  
    </field_map> 
    <failure_notification> 
     <email_address_list> 
     <email_address>bob@abc.com</email_address> 
     <email_address>orson@abc.net</email_address> 
     <email_address>FrankieJ@abcd.com</email_address> 
     </email_address_list> 
     <email_subject>Automated Data Transfer Failure</email_subject> 
     <email_body> 
      Automatic mail. 
     </email_body> 
    </failure_notification> 
    </transfer_configuration> 
    <!--A Second Server--> 
    <transfer_configuration ID="more_unique_id"> 
    <!-- ... remaining config information... --> 
    </transfer_configuration> 
</config_info> 

和XSD架构的XML。该模式是

</xsd:schema> 

但是，当我执行命令

xmlFile.Validate（ConfigValHandler），我得到的错误是“类型‘字符串’未声明，或者不是一个简单的类型。”

ConfigValHandler是XML验证的错误处理程序。 我无法找到解决方案。

Answer 1

是否将以下内容定义为字符串而不是xs：string？

“的xsd：元素的名称=‘connection_string’类型=‘字符串’”
