项目需要和别的系统交互,要求只能用XML,⊙﹏⊙b汗的很 时间不够
先通过vs 带的工具xsd.exe 命令 生成对应xml的xsd ( 打开vs 的如命令提示 xsd InpXmlSt.xsd /t:lib /l:vb /c /o:E:/Uc/操作其它进程测试3/InpOrdXmlDemo/InpXmlOpClasss)
1. 首先在VS2005中添加一个XSD文件。
2. 使用VS2005工具XSD.exe(SDK"v2.0"Bin"xsd.exe)自动生成实体类：
xsd /c /namespace:myCompany /language:CS temp1.xsd
也可以生成DataSet类型的类:
xsd /dataset /language:CS temp1.xsd
( 类文件和XSD之间可以相互转换，也就是说，你也可以先生成类，然后自动生成XSD)
自动读取XML数据到实体类：
<Serializable()> _
Public Class S01
Public Operation As Integer
Public CaseID As String
Public CreatedWhen As String
Public lsthj As New List(Of DateTime)
End Class
<Serializable()> _
Public Class ResaultInfo
Public ResultValue As Integer
Public ResultInfo As String
End Class
Public Class SerializFunc
Public Shared Function Serializ(Of T)(ByVal obj As T) As String
If Not GetType(T).IsSerializable Then
Throw New Exception(GetType(T).Name & "is not Serializ")
End If
Using memoryStream As New MemoryStream()
Dim formatter As New Serialization.XmlSerializer(GetType(T))
formatter.Serialize(memoryStream, obj)
memoryStream.Seek(0, SeekOrigin.Begin)
Dim reader As New System.IO.StreamReader(memoryStream, Encoding.UTF8)
Dim xmlstring = reader.ReadToEnd()
Return xmlstring
End Using
End Function
Public Shared Function DeSerialize(Of T)(ByVal xmlstring As String) As T
If Not GetType(T).IsSerializable Then
Throw New Exception(GetType(T).Name & "is not Serializ")
End If
Dim obj As T
Dim encoding = Text.Encoding.UTF8
Dim constructedBytes As Byte() = encoding.GetBytes(xmlstring)
Using fs As New MemoryStream(constructedBytes)
Dim formatter As New Serialization.XmlSerializer(GetType(T))
obj = DirectCast(formatter.Deserialize(fs), T)
End Using
Return obj
End Function
Public Shared Function SoapSerialize(Of T)(ByVal obj As T) As String
If Not GetType(T).IsSerializable Then
Throw New Exception(GetType(T).Name & "is not Serializ")
End If
Using memoryStream As New MemoryStream()
Dim formatter As New System.Runtime.Serialization.Formatters.Soap.SoapFormatter()
formatter.Serialize(memoryStream, obj)
memoryStream.Seek(0, SeekOrigin.Begin)
Dim reader As New System.IO.StreamReader(memoryStream, Encoding.UTF8)
Dim xmlstring = reader.ReadToEnd()
Return xmlstring
End Using
End Function
Public Shared Function SoapDeSerialize(Of T)(ByVal xmlstring As String) As T
If Not GetType(T).IsSerializable Then
Throw New Exception(GetType(T).Name & "is not Serializ")
End If
Dim obj As T
Dim encoding = Text.Encoding.UTF8
Dim constructedBytes As Byte() = encoding.GetBytes(xmlstring)
Using fs As New MemoryStream(constructedBytes)
Dim formatter As New System.Runtime.Serialization.Formatters.Soap.SoapFormatter()
obj = DirectCast(formatter.Deserialize(fs), T)
End Using
Return obj
End Function
End Class
4. 如何使用XSD来验证XML文件合法性：
- 使用XMLSpy，首先Assign XSD,然后验证 （其实就是设置XML里面引用的schema，注意schema可能引用其他的schema）
- 代码中验证：
Validate XML against XSDValidate XML against XSD#region
Validate XML against XSD
public class Validator
{
private string errMsg;
/**//**//**////
/// validation Error Msg
///
public string validationErrMsg
{ get
{ return errMsg; } set
{ errMsg = value; } }
/**//**//**////
/// Validate XML against schema
///
///
///
///
///
public bool Validate(string XSD, string XMLFile, bool LocationDefined)
{ bool isValid = true;
try
{ Stream schemaFile = null;
XmlReaderSettings settings = new XmlReaderSettings();
ValidationEventHandler SchemaValidationEventHandler = new ValidationEventHandler(ValidationCallBack);
settings.ValidationType = ValidationType.Schema;
settings.ValidationFlags |= XmlSchemaValidationFlags.AllowXmlAttributes;
settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
settings.ValidationEventHandler += SchemaValidationEventHandler;
if (LocationDefined == true)
{ settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
}
else
{ schemaFile = new FileStream(XSD, FileMode.Open);
XmlSchema tmsSchema = XmlSchema.Read(schemaFile, SchemaValidationEventHandler);
settings.Schemas.Add(tmsSchema);
}
using (XmlReader reader = XmlReader.Create(XMLFile, settings))
{ string test;
while (reader.Read() && isValid == true)
{ test = reader.Name;
}
};
if (schemaFile != null)
{ schemaFile.Close();
}
}
catch (Exception e)
{ validationErrMsg += "Exception occured when validating. " + e.Message;
isValid = false;
}
return isValid;
}
/**//**//**////
/// Display any warnings or errors.
///
///
///
public void ValidationCallBack(object sender, ValidationEventArgs args)
{ if (args.Severity == XmlSeverityType.Warning)
{ validationErrMsg += "Matching schema not found. No validation occurred." + args.Message;
validationErrMsg = args.Message;
}
else
{ validationErrMsg += "/nValidation error: " + args.Message;
validationErrMsg = args.Message;
}
}
}
