Represents a row of a DataFrame.
Is untyped, but returned values can be implicitly coerced to built-in types.

GetEnumerator
IEnumerable.GetEnumerator()
TryGetValue(
Int64, Value)Sets value to the Value of the column at the passed index (in the dataframe's basis).
If the passed index is out of bounds false is returned. Otherwise, true is returned;
TryGetValue(
String, Value)Sets value to the Value of the column with the passed name.
If the passed index is out of bounds false is returned. Otherwise, true is returned;
TryGetValue``1(
Int64, ``0)Sets value to the value of the column at the passed index (in the dataframe's basis), having coerced it to the appropriate type if possible.
If the passed index is out of bounds, or the coercing fails, false is returned. Otherwise, true is returned;
TryGetValue``1(
String, ``0)Sets value to the value of the column with the given name, having coerced it to the appropriate type if possible.
If the passed index is out of bounds, or the coercing fails, false is returned. Otherwise, true is returned;
ToArray
Converts this column to an array of Value.
Throws if the row cannot fit in an array.
ToArray(Value())
Converts this row to an array of Value.
The array is stored at index 0 in the passed array reference, which is initialized or resized if needed.
GetRange(
Int64, Int32)Converts a subset of this row to an array of Value.
Throws if the subset cannot fit in an array.
Converts a subset of this row to an array of Value.
The subset starts at the given index (in the dataframe's basis) and is of the given length.
The array is stored at index 0 in the passed array reference, which is initialized or resized if needed.
Converts a subset of this row to an array of Value.
The subset starts at the given index (in the dataframe's basis) and is of the given length.
The array is stored at the given index in the passed array reference, which is initialized or resized if needed.
Throws if subset cannot fit in an array.

Map``1
Maps this row to a TypedRow.
Map``2
Maps this row to a TypedRowType.
Map``3
Maps this row to a TypedRowType1.
Map``4
Maps this row to a TypedRowType2.
Map``5
Maps this row to a TypedRowType3.
Map``6
Maps this row to a TypedRowType4.
Map``7

op_Explicit(Row)
Equivalent to Row.ToArray()
Index
Returns the Index (in the appropriate basis) of this row in the original dataframe.
Length
Returns the number of entries in the this column. This will always match the number of columns in the original dataframe.
Item(
Int64)Return the value at the given index.
Will throw if the index is out of bounds. Use Row.TryGetValue() for non-throwing gets.
Item(
String)Return the value in the column with the given name.
Will throw if no column with that name exists . Use Row.TryGetValue() for non-throwing gets.
