This project is read-only.
DataSet supports variables of the following types:
  • Double
  • Single
  • Int16
  • Int32
  • Int64
  • UInt64
  • UInt32
  • UInt16
  • Byte
  • SByte
  • DateTime
  • String
  • Boolean
Note that Char is not supported.

If you try to create a variable of a type that is not listed in the list, the exception InvalidOperationException occurs. The static method DataSet.IsSupported(Type) makes a dynamic check to determine whether a type is supported.

Variable metadata is a dictionary of keys and values and is represented by the class MetadataDictionary.

A key is a string of 256 characters or less. A metadata key cannot be null or an empty string and cannot contain the following Unicode symbols: '/', '0x00'-'0x1F', '0x7F'-'0xFF'.

A value is an instance of any supported type or a one-dimensional array of such a type.
