DataSet.Namespace Property

Definition

Namespace:

System.Data

Assemblies:

netstandard.dll, System.Data.Common.dll

Source:

DataSet.cs

Gets or sets the namespace of the DataSet.

C#

public string Namespace { get; set; }

Property Value

String

The namespace of the DataSet.

Exceptions

ArgumentException

The namespace already has data.

Examples

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

C#

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);
}

Remarks

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.
