Equality 运算符 (DacInstance.Key, Object)
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, _
obj As Object _
) As Boolean
用法
Dim leftOperand As DacInstance..::..Key
Dim obj As Object
Dim returnValue As Boolean
returnValue = (leftOperand = obj)
public static bool operator ==(
DacInstance..::..Key leftOperand,
Object obj
)
public:
static bool operator ==(
DacInstance..::..Key^ leftOperand,
Object^ obj
)
static let inline (=)
leftOperand:DacInstance..::..Key *
obj:Object : 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
- leftOperand
类型:Microsoft.SqlServer.Management.Dac. . :: . .DacInstance. . :: . .Key
A DacInstance..::..Key object representing one of the DAC instances to compare.
- obj
类型:System. . :: . .Object
A Object object representing the other DAC instance to compare. If the object does not reference a DacInstance..::..Key, the method returns False.
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.
