创建一个 DbFunctionExpression，它使用指定的参数（每个参数都必须具有字符串结果类型）调用规范“Replace”函数。该表达式的结果类型也为字符串。

public:
[System::Runtime::CompilerServices::Extension]
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ Replace(System::Data::Common::CommandTrees::DbExpression ^ stringArgument, System::Data::Common::CommandTrees::DbExpression ^ toReplace, System::Data::Common::CommandTrees::DbExpression ^ replacement);

public static System.Data.Common.CommandTrees.DbFunctionExpression Replace (this System.Data.Common.CommandTrees.DbExpression stringArgument, System.Data.Common.CommandTrees.DbExpression toReplace, System.Data.Common.CommandTrees.DbExpression replacement);

static member Replace : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression

<Extension()>
Public Function Replace (stringArgument As DbExpression, toReplace As DbExpression, replacement As DbExpression) As DbFunctionExpression
