The ConstraintException type exposes the following members.
| Name | Description | |

ConstraintException() | Initializes a new instance of the ConstraintException class. This is the default constructor. |
|
|
ConstraintException(String) | Initializes a new instance of the ConstraintException class with the specified string. |
|
ConstraintException(SerializationInfo, StreamingContext) | Initializes a new instance of the ConstraintException class using the specified serialization and stream context. |
|
|
ConstraintException(String, Exception) | Initializes a new instance of the ConstraintException class using the specified string and inner exception. |
| Name | Description | |
|---|---|---|
|
Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
|
|
HelpLink | Gets or sets a link to the help file associated with this exception. (Inherited from Exception.) |
|
HResult | Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.) |
|
|
InnerException | Gets the Exception instance that caused the current exception. (Inherited from Exception.) |
|
|
Message | Gets a message that describes the current exception. (Inherited from Exception.) |
|
|

|
GetObjectData | When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception.) |

Troubleshooting Suggestion
You can easily diagnose and fix this, generally, by calling GetErrors on the DataTable that threw this exception -- provided of course that you break into the debugger as soon as the exception is thrown. This method will return all rows with errors, and you can inspect the Error property on each to get a useful message that will point you in the right direction. Nine times out of ten it's usually something simple like a null when it's marked not null or exceeding the MaxLength value.
