how to solve exception of type 'system.outofmemoryexception' was throw

The System.OutOfMemoryException in C# is thrown when the common language runtime (CLR) is unable to allocate enough memory for an operation.

To fix System.OutOfMemoryException in C#:

• Use 64-bit process: Allows access to more memory.
• Stream large files: Avoid loading entire files or datasets into memory.
• Avoid large allocations: Break data into smaller chunks.
• Dispose unmanaged resources: Release memory for images, files, etc.
• Use memory profilers: Find leaks or heavy memory use.
• Avoid unnecessary ToList()/ToArray() on large data.
