键入的DataSet架构 [英] Typed DataSet Schema

问题描述

我创建了一个类型化数据集..添加 - >新项目 - > DataSet1.xsd ..



我在数据表中添加了两列。



现在我的xsd架构如下所示。

<？xml version =" 1.0"编码= QUOT; UTF-8英寸？>

- < xs：schema id =" SampleDataSet"的targetNamespace = QUOT; HTTP：//tempuri.org/SampleDataSet.xsd"的xmlns：mstns = QUOT; HTTP：//tempuri.org/SampleDataSet.xsd"的xmlns = QUOT; HTTP：//tempuri.org/SampleDataSet.xsd"的xmlns：XS = QUOT; HTTP：//www.w3.org/2001/XMLSchema"的xmlns：MSDATA = QUOT;瓮：架构 - 微软-COM：XML-MSDATA"

我在模式中看到一些额外的行和属性..如何避免这种情况......我是引用此链接.Dataset架构应该是这样的..

i have created a typed dataset.. Add-->New Item-->DataSet1.xsd..

And i have added two columns in the datatable.

Now my xsd schema is looking like below.

<?xml version="1.0" encoding="utf-8" ?>
- <xs:schema id="SampleDataSet" targetNamespace="http://tempuri.org/SampleDataSet.xsd" xmlns:mstns="http://tempuri.org/SampleDataSet.xsd" xmlns="http://tempuri.org/SampleDataSet.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop" attributeFormDefault="qualified" elementFormDefault="qualified">
- <xs:annotation>
- <xs:appinfo source="urn:schemas-microsoft-com:xml-msdatasource">
- <DataSource DefaultConnectionIndex="0" FunctionsComponentName="QueriesTableAdapter" Modifier="AutoLayout, AnsiClass, Class, Public" SchemaSerializationMode="IncludeSchema" xmlns="urn:schemas-microsoft-com:xml-msdatasource">
<Connections />
<Tables />
<Sources />
</DataSource>
</xs:appinfo>
</xs:annotation>
- <xs:element name="SampleDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true" msprop:Generator_DataSetName="SampleDataSet" msprop:Generator_UserDSName="SampleDataSet" msprop:EnableTableAdapterManager="true">
- <xs:complexType>
- <xs:choice minOccurs="0" maxOccurs="unbounded">
- <xs:element name="SampleDataTable" msprop:Generator_UserTableName="SampleDataTable" msprop:Generator_RowDeletedName="SampleDataTableRowDeleted" msprop:Generator_TableClassName="SampleDataTableDataTable" msprop:Generator_RowChangedName="SampleDataTableRowChanged" msprop:Generator_RowClassName="SampleDataTableRow" msprop:Generator_RowChangingName="SampleDataTableRowChanging" msprop:Generator_RowEvArgName="SampleDataTableRowChangeEvent" msprop:Generator_RowEvHandlerName="SampleDataTableRowChangeEventHandler" msprop:Generator_TablePropName="SampleDataTable" msprop:Generator_TableVarName="tableSampleDataTable" msprop:Generator_RowDeletingName="SampleDataTableRowDeleting">
- <xs:complexType>
- <xs:sequence>
<xs:element name="Column1" msprop:Generator_UserColumnName="Column1" msprop:Generator_ColumnPropNameInRow="Column1" msprop:Generator_ColumnVarNameInTable="columnColumn1" msprop:Generator_ColumnPropNameInTable="Column1Column" type="xs:string" minOccurs="0" />
<xs:element name="Column2" msprop:Generator_UserColumnName="Column2" msprop:Generator_ColumnPropNameInRow="Column2" msprop:Generator_ColumnVarNameInTable="columnColumn2" msprop:Generator_ColumnPropNameInTable="Column2Column" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>


I am seeing some extra rows and properties in my schema..How to avoid this..I am refering this link..Dataset schema should be like this..
