IEnumerable<T> sequence
)
Parameters
- sequence IEnumerable<T>
- A sequence of objects of type T.
Type Parameters
- T
- The type of the objects.
Return Value
DataFrame<Int64, String>A data frame whose columns contain the values of the properties of the objects in sequence.
FromObjects<T>(IEnumerable<T>, String[])
Creates a new data frame containing the specified properties of a sequence of objects.
public static DataFrame<long, string> FromObjects<T>(
IEnumerable<T> sequence,
params string[] propertyNames
)
Parameters
- sequence IEnumerable<T>
- A sequence of objects of type T.
- propertyNames String[]
- A parameter array of strings that contains the names of the properties to include in the data frame.
Type Parameters
- T
- The type of the objects.
Return Value

FromObjects<T, R>(IEnumerable<T>, String)
Creates a new data frame containing the public properties of a sequence of objects.
public static DataFrame<R, string> FromObjects<T, R>(
IEnumerable<T> sequence,
string rowKeyProperty
)
Parameters
- sequence IEnumerable<T>
- A sequence of objects of type T.
- rowKeyProperty String
- The name of the property that contains the row keys.
Type Parameters
- T
- The type of the objects.
