SystemException()
- Source:
- SystemException.cs
- Source:
- SystemException.cs
- Source:
- SystemException.cs
Initializes a new instance of the SystemException class.
public:
SystemException();public SystemException ();Public Sub New ()Remarks
This constructor initializes the Message property of the new instance to a system-supplied message that describes the error, such as "A system error has occurred." This message takes into account the current system culture.
The following table shows the initial property values for an instance of SystemException.
| Property | Value |
|---|---|
| InnerException | A null reference (Nothing in Visual Basic). |
| Message | The localized error message string. |
Applies to
SystemException(String)
- Source:
- SystemException.cs
- Source:

Initializes a new instance of the SystemException class with a specified error message.
public:
SystemException(System::String ^ message);public SystemException (string? message);public SystemException (string message);new SystemException : string -> SystemExceptionPublic Sub New (message As String)Parameters
- message
- String
The message that describes the error.
Remarks
The content of the message parameter should be understandable to the user. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

Caution
This API supports obsolete formatter-based serialization. It should not be called or extended by application code.
Initializes a new instance of the SystemException class with serialized data.
protected:
SystemException(System::Runtime::Serialization::SerializationInfo ^ info, System::Runtime::Serialization::StreamingContext context);protected SystemException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);[System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
protected SystemException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);new SystemException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> SystemException[<System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
new SystemException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> SystemExceptionProtected Sub New (info As SerializationInfo, context As StreamingContext)Parameters
- info
- SerializationInfo
The object that holds the serialized object data.
- context
- StreamingContext
The contextual information about the source or destination.
- Attributes
Remarks
This constructor is called during deserialization to reconstitute the exception object transmitted over a stream. For more information, see XML and SOAP Serialization.

Applies to
SystemException(String, Exception)
- Source:
- SystemException.cs
- Source:
- SystemException.cs
- Source:
- SystemException.cs
Initializes a new instance of the SystemException class with a specified error message and a reference to the inner exception that is the cause of this exception.
public:
SystemException(System::String ^ message, Exception ^ innerException);public SystemException (string? message, Exception? innerException);public SystemException (string message, Exception innerException);new SystemException : string * Exception -> SystemExceptionPublic Sub New (message As String, innerException As Exception)Parameters
- message
- String
The error message that explains the reason for the exception.
- innerException
- Exception
The exception that is the cause of the current exception. If the innerException parameter is not a null reference (Nothing in Visual Basic), the current exception is raised in a catch block that handles the inner exception.
Remarks
An exception that is thrown as a direct result of a previous exception can include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or a null reference (Nothing in Visual Basic) if the InnerException property does not supply the inner exception value to the constructor.
The following table shows the initial property values for an instance of SystemException.
| Property | Value |
|---|---|
| InnerException | The inner exception reference. |
| Message | The error message string. |
