联接另一列 DataFrame

public Microsoft.Data.Analysis.DataFrame Join(Microsoft.Data.Analysis.DataFrame other, string leftSuffix = "_left", string rightSuffix = "_right", Microsoft.Data.Analysis.JoinAlgorithm joinAlgorithm = Microsoft.Data.Analysis.JoinAlgorithm.Left);

member this.Join : Microsoft.Data.Analysis.DataFrame * string * string * Microsoft.Data.Analysis.JoinAlgorithm -> Microsoft.Data.Analysis.DataFrame

Public Function Join (other As DataFrame, Optional leftSuffix As String = "_left", Optional rightSuffix As String = "_right", Optional joinAlgorithm As JoinAlgorithm = Microsoft.Data.Analysis.JoinAlgorithm.Left) As DataFrame

参数

other: DataFrame

要加入的另一个 DataFrame 。

leftSuffix: String

如果存在公用列名称，则要添加到此 DataFrame列的后缀

rightSuffix: String

如果存在公用列名称， other则要添加到“列”的后缀

joinAlgorithm: JoinAlgorithm

要使用的 JoinAlgorithm。

返回

新的 DataFrame
