DataSet.Namespace Property

Gets or sets the namespace of the DataSet.

Namespace:  System.Data
Assembly:  System.Data (in System.Data.dll)

public string Namespace { get; set; }

Property Value

Type: System.String
The namespace of the DataSet.

ExceptionCondition
ArgumentException

The namespace already has data.

The Namespace property is used when reading and writing an XML document into the DataSet using the ReadXml, WriteXml, ReadXmlSchema, or WriteXmlSchema methods.

The namespace of an XML document is used to scope XML attributes and elements when read into a DataSet. For example, if a DataSet contains a schema that was read from a document with the namespace "myCompany," and an attempt is made to read data only from a document with a different namespace, any data that does not correspond to the existing schema is ignored.

The following example sets the Prefix before calling the ReadXml method.

private void ReadData(DataSet thisDataSet)
{
    thisDataSet.Namespace = "CorporationA";
    thisDataSet.Prefix = "DivisionA";

    // Read schema and data. 
    string fileName = "CorporationA_Schema.xml";
    thisDataSet.ReadXmlSchema(fileName);
    fileName = "DivisionA_Report.xml";
    thisDataSet.ReadXml(fileName);
}
