Equality 运算符 (DacInstance.Key, DacInstance.Key)

Performs a Boolean equality operation to determine whether two DACInstance keys reference the same DAC instance.

命名空间：  Microsoft.SqlServer.Management.Dac
程序集：  Microsoft.SqlServer.Management.Dac（在 Microsoft.SqlServer.Management.Dac.dll 中）

语法

声明
Public Shared Operator = ( _
    leftOperand As DacInstance..::..Key, _
    rightOperand As DacInstance..::..Key _
) As Boolean
用法
Dim leftOperand As DacInstance..::..Key
Dim rightOperand As DacInstance..::..Key
Dim returnValue As Boolean

returnValue = (leftOperand = rightOperand)

public static bool operator ==(
    DacInstance..::..Key leftOperand,
    DacInstance..::..Key rightOperand
)

public:
static bool operator ==(
    DacInstance..::..Key^ leftOperand, 
    DacInstance..::..Key^ rightOperand
)

static let inline (=)
        leftOperand:DacInstance..::..Key * 
        rightOperand:DacInstance..::..Key  : bool

JScript 支持使用重载的运算符，但不支持声明新重载运算符。

参数

返回值

类型：System. . :: . .Boolean
A Boolean value specifying whether the two DAC instances are the same. Returns True if both parameters are null or reference the same DAC instance. Otherwise, returns False.
