  [A]DevExpress.XtraLayout.LayoutControl 无法强制转换为 [B]DevExpress.XtraLayout.LayoutControl。类型 A 源自“DevExpress.XtraLayout.v21.2, Version=21.2.10.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a”(在上下文“LoadNeither”中的“C:\Users\admin\AppData\Local\Microsoft\VisualStudio\16.0_60b67fd4\ProjectAssemblies\9at2pqcv01\DevExpress.XtraLayout.v21.2.dll”位置处)。类型 B 源自“DevExpress.XtraLayout.v21.2, Version=21.2.4.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a”(在上下文“Default”中的“C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\DevExpress.XtraLayout.v21.2\v4.0_21.2.4.0__b88d1754d700e49a\DevExpress.XtraLayout.v21.2.dll”位置处)。
