  • 参考

定义

命名空间:
Microsoft.Data.Analysis
程序集:
Microsoft.Data.Analysis.dll
包:
Microsoft.Data.Analysis v0.21.1

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
