# Moq1002: Parameters provided into mock do not match any existing constructors

---
In order to construct the mocked type, constructor parameters must match a constructor. To fix:
- Match the arguments to `Mock` with a constructor of the mocked type
## Examples of patterns that are flagged by this analyzer
```csharp
class MyClass
{
MyClass(string s) { }
}
var mock = new Mock<MyClass>(3); // Moq1002: Parameters provided into mock do not match any existing constructors
```
## Solution
```csharp
class MyClass
{
MyClass(string s) { }
}
var mock = new Mock<MyClass>("three");
```
## Suppress a warning
If you just want to suppress a single violation, add preprocessor directives to
your source file to disable and then re-enable the rule.
```csharp
#pragma warning disable Moq1002
var mock = new Mock<MyClass>(3); // Moq1002: Parameters provided into mock do not match any existing constructors
#pragma warning restore Moq1002
```
To disable the rule for a file, folder, or project, set its severity to `none`
in the
[configuration file](https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/configuration-files).
```ini
[*.{cs,vb}]
dotnet_diagnostic.Moq1002.severity = none
```
