yxdb-net

yxdb-net is a library for reading YXDB files into .NET applications.

Install from NuGet. The package is compiled against .NET Standard 2.0.

The library has 1 depdency to Microsoft's System.Text.Json package and is a pure C# solution.

The public API is contained in the YxdbReader class. Instantiate YxdbReader using one of the two constructors:

• new YxdbReader(String) - load from a file
• new YxdbReader(Stream) - load from an in-memory stream

Iterate through the records in the file using the next() method in a while loop:

while (reader.Next()) {
    // do something
}

Fields can be access via the readX() methods on the YxdbReader class. There are readers for each kind of data field supported by YXDB files:

• ReadByte() - read Byte fields
• ReadBlob() - read Blob and SpatialObj fields
• ReadBool() - read Bool fields
• ReadDate() - read Date and DateTime fields
• ReadDouble() - read FixedDecimal, Float, and Double fields
• ReadLong() - read Int16, Int32, and Int64 fields
• ReadString() - read String, WString, V_String, and V_WString fields

Each read method has 2 overloads:

• ReadX(int index) - read by field index number
• ReadX(String name) - read by field name

If either the index number or field name is invalid, the read methods will throw an exception.

To read spatial objects, use the yxdb.Spatial.ToGeoJson() function. The ToGeoJson() function translates the binary SpatialObj format into a GeoJSON string.
