C#
public int CompareTo(OpcModifiedHistoryValue other)
Parameters
other
OpcModifiedHistoryValue
The OpcModifiedHistoryValue to compare with this OpcModifiedHistoryValue.
Returns
A 32-bit signed integer that indicates the relative order of the objects being compared (CompareTo(0)).
Determines whether the specified other
is equal to this OpcModifiedHistoryValue.
C#
public override bool Equals(object other)
Parameters
other
Object
The OpcModifiedHistoryValue to compare to the current OpcModifiedHistoryValue.
Returns
The value true if the specified OpcModifiedHistoryValue is equal to the current OpcModifiedHistoryValue; otherwise the value false.
Determines whether the specified other
is equal to this OpcModifiedHistoryValue.
C#
public bool Equals(OpcModifiedHistoryValue other)
Parameters
other
OpcModifiedHistoryValue
The OpcModifiedHistoryValue to compare to the current OpcModifiedHistoryValue.
Returns
The value true if the specified OpcModifiedHistoryValue is equal to the current OpcModifiedHistoryValue; otherwise the value false.
Retrieves a hash code for this OpcModifiedHistoryValue.
C#
public override int GetHashCode()
Returns
An Int32 that contains the hash code for the OpcModifiedHistoryValue.
Returns a value indicating whether two instance of OpcModifiedHistoryValue are equal.
C#
public static bool operator ==(OpcModifiedHistoryValue left, OpcModifiedHistoryValue right)
Determines whether the first specified OpcModifiedHistoryValue object is greater than the second specified OpcModifiedHistoryValue object.
C#
public static bool operator>(OpcModifiedHistoryValue left, OpcModifiedHistoryValue right)
Determines whether the first specified OpcModifiedHistoryValue object is greater than or equal to the second specified OpcModifiedHistoryValue object.
C#
public static bool operator >=(OpcModifiedHistoryValue left, OpcModifiedHistoryValue right)
Returns a value indicating whether two instances of OpcModifiedHistoryValue are not equal.
C#
public static bool operator !=(OpcModifiedHistoryValue left, OpcModifiedHistoryValue right)
Determines whether the first specified OpcModifiedHistoryValue object is less than the second specified OpcModifiedHistoryValue object.
C#
public static bool operator <(OpcModifiedHistoryValue left, OpcModifiedHistoryValue right)
Exceptions
The left
is a null reference (Nothing in Visual Basic).
Determines whether the first specified OpcModifiedHistoryValue object is less than or equal to the second OpcModifiedHistoryValue object.
C#
public static bool operator <=(OpcModifiedHistoryValue left, OpcModifiedHistoryValue right)
Exceptions
The left
is a null reference (Nothing in Visual Basic).
